Abstract To enhance heat dissipation of a coil in a reactor, while surely assembling a bobbin to which the coil is wound.SOLUTION: A bobbin 14 structuring a reactor 10, is formed by first and second holders 26 and 28 coating a coil 12 engaged in an axial direction along a center of winding of the coil 12. The first holder 26 comprises: an inner peripheral wall 30 arranged in an inner periphery of the coil 12; and first and second flanges 32 and 34 formed on one end and the other end to the axial direction of the inner peripheral wall 30. In the first flange 32, a first circular ring part 38 on an outer peripheral side is formed thickly to each first cross-linkage part 36 provided to an inner peripheral side. In the first circular ring part 38, a plurality of concave parts concaved to the axial direction is formed, and an engagement hole engaging with a claw part of the second holder 28 is formed on a bottom face of each concave part, and a plurality of first exposure holes 40 exposing a part of the coil 12 is provided between the first cross-linkage parts 36.SELECTED DRAWING: Figure 5 【課題】リアクトルにおいてコイルの巻回されたボビンを確実に組み付けると共にコイルの放熱性を高める。【解決手段】リアクトル10を構成するボビン14は、コイル12の巻回中心に沿った軸方向に係合されコイル12を覆う第1及び第2ホルダ26、28からなり、第1ホルダ26には、コイル12の内周に配置される内周壁30と、該内周壁30の軸方向一端及び他端に形成された第1及び第2フランジ32、34とを備えている。第1フランジ32において、外周側の第1円環部38が内周側に設けられた第1架橋部36に対して厚く形成され、第1円環部38には、軸方向に窪んだ複数の凹部が形成され、該凹部の底面に第2ホルダ28の爪部と係合する係合孔が形成されると共に、第1架橋部36の間には、コイル12の一部を露出させる複数の第1露出孔40が設けられている。【選択図】図5
