Zusammenfassung:To reduce the overall height of a coil component.SOLUTION: A coil component 1 includes a coil part 3 and a conductor post P1 embedded in a magnetic element assembly M, a post protection film 15 provided between the conductor post P1 and the magnetic element assembly M, a cover insulating film 21 that covers a mount surface 4 of the magnetic element assembly M, and a terminal electrode E1 connected to the conductor post P1 through an opening 21a provided in the cover insulating film 21. The mount surface 4 of the magnetic element assembly M includes a concave part 4a and the terminal electrode E1 is accommodated in the concave part 4a. This makes it possible to reduce the overall height and prevent the short-circuit failure.SELECTED DRAWING: Figure 2 【課題】コイル部品の全体の高さを低背化する。【解決手段】コイル部品1は、磁性素体Mに埋め込まれたコイル部3及び導体ポストP1と、導体ポストP1と磁性素体Mの間に設けられたポスト保護膜15と、磁性素体Mの実装面4を覆うカバー絶縁膜21と、カバー絶縁膜21に設けられた開口21aを介して導体ポストP1に接続された端子電極E1とを備える。磁性素体Mの実装面4は凹部4aを有し、端子電極E1は凹部4aに収容されている。これにより、全体の高さを低背化することができるとともに、ショート不良を防止することが可能となる。【選択図】図2
