To obtain a cooling effect and an electromagnetic shield effect for a planar type magnetic device installed in a horizontal direction.SOLUTION: A heat sink 6 includes a recess 6a having a substrate facing surface 6b facing one surface of a substrate 5a, and a core facing surface 6c facing one surface of a core 5h at a position deeper than the substrate facing surface 6b. A metal pressing member 8 presses a magnetic device 5 housed in the recess 6a in a state where an opening of the recess 6a is shielded to bring one surface of the substrate 5a into contact with the substrate facing surface 6b, and presses one surface of the core 5h toward the core facing surface 6c.SELECTED DRAWING: Figure 2 【課題】横向きに設置されたプレーナ型の磁気装置に対する冷却効果及び電磁シールド効果を得る。【解決手段】ヒートシンク６は、基板５ａの片面に対向する基板対向面６ｂと、基板対向面６ｂよりも深い位置でコア５ｈの片面に対向するコア対向面６ｃとが形成された凹部６ａを有する。金属製の押圧部材８は、凹部６ａの開口部を遮蔽した状態で、凹部６ａに収容された磁気装置５を押圧することにより基板５ａの片面を基板対向面６ｂに当接させると共にコア５ｈの片面をコア対向面６ｃに向けて押圧する。【選択図】図２
