Chip inductor and manufacturing method thereof
Abstract:
To provide a chip inductor, which can make magnetic loss of the inductor element reduced, excellent in electrical property such as high Q etc., and high reliability, which is demanded for use in vehicles. The chip inductor comprises a ferrite core (11) comprising an axial section (11a), flange portions (11b) disposed at both ends of the axial section, and concavities (11c) opened for direction of the axial section on at least one face of the flange section; an internal electrode (13) consisting of metallic plate having a notch portion at axial section side, the internal electrode fixed on the upper face of the flange section having the concavity; and a winding (12) wound around the axial section of the ferrite core; wherein an end portion of the winding (12a) comes in contact to a side of the concavity, which faces to the axial section, comes in contact to the notch portion of the internal electrode, and is fixed on upper face of the internal electrode.
