COIL COMPONENT AND COIL MODULE

To improve a coil component including a coil pattern provided on a substrate and a magnetic material layer covering the substrate.SOLUTION: A coil component 1 includes a substrate 10, a coil pattern 30 provided on one surface 11 of the substrate 10, and a magnetic material layer 20 covering the other surface 12 of the substrate 10. A laminated body S of the substrate 10 and the magnetic material layer 20 has a through-hole 40 provided on an open area 31a of the coil pattern 30. On this same basis, even if electronic components such as IC modules are arranged in the through-hole 40, there is no interference between the electronic components and the substrate 10.SELECTED DRAWING: Figure 1 【課題】基材に設けられたコイルパターン及び基材を覆う磁性体層を備えるコイル部品を改良する。【解決手段】コイル部品１は、基材１０と、基材１０の一方の表面１１に設けられたコイルパターン３０と、基材１０の他方の表面１２を覆う磁性体層２０とを備える。基材１０と磁性体層２０の積層体Ｓは、コイルパターン３０の開口領域３１ａに設けられた貫通孔４０を有する。これによれば、貫通孔４０内にＩＣモジュールなどの電子部品を配置しても、電子部品と基材１０が干渉することがない。【選択図】図１
