COIL COMPONENT AND ELECTRONIC APPARATUS

To provide a coil component and an electronic apparatus, capable of suppressing a decrease in reliability while reducing the use amount of a resin.SOLUTION: A coil component includes: a base part including metal magnetic particles, a gap between the metal magnetic particles, and a resin filling the gap; and a coil conductor built in the base part and formed of multi-layer conductors. In the cross section of the base part along a coil axis, the base part has: a first region of the base part sandwiched between the multi-layer conductors; and a second region of the base part orthogonal to the coil axis on at lest one side of the inside or outside from the conductors. The first region and the second region include a filling part where the gap is filled with the resin, and a non-filling part where the gap is not filled with the resin. The ratio of the filling part and the non-filling part is such that the filling part is 90% or more in the first region and 80% or less in the second region.SELECTED DRAWING: Figure 3 【課題】樹脂の使用量を低く抑えつつ、信頼性の低下を抑制すること。【解決手段】金属磁性粒子と、前記金属磁性粒子の間の隙間と、前記隙間を埋める樹脂と、を含む基体部と、前記基体部に内蔵され、複数層の導体で形成されるコイル導体と、を備え、コイル軸に沿った前記基体部の断面において、前記基体部は、前記複数層の導体の間に挟まれる前記基体部の第１領域と、前記コイル軸に直交し、前記導体から内側もしくは外側の少なくても一方の側にある前記基体部の第２領域と、を有し、前記第１領域及び前記第２領域は前記隙間が前記樹脂で埋められる充填部と、前記隙間が前記樹脂で埋められない非充填部を含み、前記充填部と前記非充填部との割合は第１領域で９０％以上が前記充填部であり、前記第２領域で８０％以下が前記充填部である、コイル部品。【選択図】図３
