Abstract: An electronic device includes a chip component and a metal terminal. The chip component includes a terminal electrode formed on an element body. The metal terminal is connectable with the terminal electrode of the chip component. The metal terminal includes a terminal body and a pair of holding pieces. The terminal body faces an end surface of the terminal electrode of the chip component. The pair of holding pieces is formed on the terminal body and sandwiches the chip component. A width, a protrusion length, or a protrusion area of one of the pair of holding pieces is different from that of the other holding piece.

Abstract: A ceramic electronic device includes a chip component, a metal terminal, and a conductive connection member. The component includes a terminal electrode surface on which a terminal electrode is formed. The metal terminal includes an opposing surface to the electrode surface. The connection member contains at least Sn and Sb and connects the terminal electrode surface and the opposing surface. The connection member includes a first part and a second part. In the first part, a distance between the terminal electrode surface and the opposing surface is a first distance, and Sb/Sn is a first value. In the second part, a distance between the terminal electrode surface and the opposing surface is a second distance being smaller than the first distance, and Sb/Sn is a second value being larger than the first value.

Abstract: A ceramic electronic device includes multiple chip components and a pair of metal terminal portions. The chip components consist of a pair of chip end surfaces and four chip side surfaces. Terminal electrodes are formed on the pair of chip end surfaces. The pair of metal terminal portions is arranged correspondingly with the pair of chip end surfaces. Each of the pair of metal terminal portions includes an electrode face portion, a pair of engagement arm portions, and a mount portion. The electrode face portion faces the chip end surface. The pair of engagement arm portions sandwich and hold the chip component. The mount portion extends from one of terminal second sides toward the chip component and is partially substantially vertical to the electrode face portion. The electrode face portion has a slit.

The terminal body faces an end surface of the terminal electrode of the chip component. The holding pieces are formed on the terminal body. A connection member configured to connect the terminal body and the end surface of the terminal body exists in a joint region between the terminal body and the end surface of the terminal electrode. A pair of reinforcement pieces is formed on the terminal body so as not to overlap with the joint region in a direction extending from one to the other of the pair of holding pieces.

Abstract: An electronic device includes a chip component and a metal terminal. The chip component has an element body where internal electrodes are laminated inside and a terminal electrode formed outside the element body and connected with end parts of the internal electrodes. The metal terminal is connected with the terminal electrode of the chip component. The metal terminal includes an electrode face portion and a mount portion. The electrode face portion is arranged correspondingly with an end surface of the terminal electrode. The mount portion is mounted on a mount surface. The electrode face portion is provided with an opening portion so that a part of the terminal electrode corresponding with at least a part of the internal electrodes is exposed to the outside.

Abstract: An electronic device includes a chip component and a metal terminal. The chip component includes an element body containing laminated internal electrodes and a terminal electrode formed outside the element body to connect with ends of the internal electrodes. The metal terminal is connectable with the terminal electrode of the chip component. The metal terminal includes an electrode facing portion, a holding portion, and a mount portion. A connection member connecting between the electrode facing portion and the end surface of the terminal electrode exists in a joint region in a predetermined range. A non-joint region is formed between an edge of the joint region and the holding portion. A non-joint gap between the electrode facing portion and the end surface of the terminal electrode becomes larger toward the holding portion in the non-joint region.

Abstract: An electronic device includes a chip component and a metal terminal. The metal terminal is connected with the chip component. The metal terminal includes an electrode facing portion and a holding portion. The electrode facing portion is arranged correspondingly with an end surface of the terminal electrode of the chip component. The holding portion holds the chip component. A space region between the electrode facing portion and the end surface of the terminal electrode includes a joint region and a non-joint region. In the joint region, a connection member connects the electrode facing portion and the end surface of the terminal electrode.
