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: A metal terminal is connectable to terminal electrodes of chip components arranged side by side. The metal terminal includes units corresponding to each chip. Each unit includes an electrode facing portion, a pair of upper and lower holding portions, a mount portion, and protrusions. The electrode facing portion faces the electrode of the chip. The pair of upper and lower holding portions holds the chip. The mount portion is located below the lower holding portion of the electrode facing portion. The protrusions protrude from the electrode facing portion toward the electrode. The protrusions in each unit are arranged substantially line-symmetrically to a virtual center line passing through a middle point between the upper and lower holding portions.

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 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.
