Patent ID: 11621117

Abstract:
A wire wound-type coil component with an integrated structure does not have a bonding portion where there is concern about reliability with respect to a spiral conductive wire, a terminal electrode, and an annular core. A coil component includes a core with an integrated structure, at least part of which is a winding core portion, which has an annular shape having a through-hole, and which is made of a non-conductive material; and a coil conductor with an integrated structure, which has a spiral conductive wire arranged to spirally extend around the winding core portion and first and second terminal electrodes formed at both end portions of the spiral conductive wire, respectively. The coil component is manufactured through three-dimensionally shaping the core, the coil conductor, and a shape holding member for holding a shape of a wall surface of the core defining the through-hole, by using a 3D printer.
