COIL COMPONENT AND MANUFACTURING METHOD FOR THE SAME

To reduce the connection resistance between a conductor post and a terminal electrode while increasing the insulating property between the terminal electrode and a magnetic element assembly.SOLUTION: A coil component 1 includes a coil part 3 and a conductor post P1 embedded in a magnetic element assembly M, a cover insulating film 21 that covers a mount surface 4, and a terminal electrode E1 connected to the conductor post P1 through an opening 21a. The terminal electrode E1 includes a conductor layer 31 in contact with the conductor post P1 through the opening 21a, and a conductor layer 32 formed of a conductive material with a lower resistance value than the conductor layer 31, covering a surface of the conductor layer 31, and being in contact with the conductor post P1 through the opening 31a. This makes it possible to reduce the contact resistance between the conductor post P1 and the terminal electrode E1 while increasing the insulating property between the terminal electrode E1 and the magnetic element assembly M.SELECTED DRAWING: Figure 2 【課題】端子電極と磁性素体の絶縁性を高めつつ、導体ポストと端子電極の接続抵抗を低減する。【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、実装面４を覆うカバー絶縁膜２１と、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。端子電極Ｅ１は、開口２１ａを介して導体ポストＰ１と接する導体層３１と、導体層３１よりも抵抗値の低い導電材料からなり、導体層３１の表面を覆うとともに、開口３１ａを介して導体ポストＰ１と接する導体層３２とを含む。これにより、端子電極Ｅ１と磁性素体Ｍの絶縁性を高めつつ、導体ポストＰ１と端子電極Ｅ１の接続抵抗を低減することができる。【選択図】図２
