INDUCTOR AND MANUFACTURING METHOD THEREFOR

摘要

An inductor provided with the following: an inductor core comprising two U-shaped core members arranged in a ring with gaps therebetween, said gaps containing adhesive layers; primary insert-molded resin parts that cover the outside surfaces of the leg parts of the core members except for the surfaces where the core members are bonded to each other, at least, and include coupling parts formed around the leg end faces to be bonded to each other; coils disposed around the abovementioned gaps and the legs of the core members; and secondary insert-molded resin parts comprising a thermoplastic resin that is insert-molded around the coils so as to affix said coils to the inductor core and affixes the leg parts of the two core members to each other. With the core members arranged so as to form a ring, the coupling parts of the primary insert-molded resin parts are fitted to each other, forming walls that enclose the abovementioned gaps. This makes it possible to securely bond the inductor core together without requiring jigs to hold said inductor core.
