| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a coil bobbin formed by injection molding with high productivity and also to provide a coil device for an antenna using such a coil bobbin.SOLUTION: A coil device 100 includes: a core 10 formed of a magnetic material; a coil bobbin 20 having a winding shaft 22 and attached to the periphery of the core 10; and a coil wire 50 wound around the winding shaft 22. The coil bobbin 20 is formed of one component integrally molded with a resin material and constituted so that projection to any region of the coil bobbin 20 is also prevented from being overlapped on the other region of the coil bobbin 20 in at least one direction (X direction) intersecting with the extension direction of the winding shaft 22.
【課題】射出成形による生産性の高いコイルボビン、およびかかるコイルボビンを用いたアンテナ用コイル装置を提供する。【解決手段】コイル装置１００は、磁性材料からなるコア１０と、巻軸部２２を有しコア１０の周囲に装着されるコイルボビン２０と、巻軸部２２に巻回されたコイルワイヤ５０と、を備えている。コイルボビン２０は、樹脂材料で一体成形された一部品からなるとともに、巻軸部２２の延在方向に対して交差する少なくとも一の方向（Ｘ方向）に関して、コイルボビン２０のいずれの領域への投影もコイルボビン２０の他の領域と重ならないように構成されている。【選択図】図１ |
