INDUCTOR AND MANUFACTURING METHOD FOR THE SAME

To provide an inductor in which an eddy current to be generated is reduced.SOLUTION: An inductor 101 comprises: a substrate 1 having a main surface 1u; a magnetic core 5 arranged along a coil axis parallel with the main surface 1u on the main surface 1u; and a coil conductor 2 surrounding the magnetic core 5 in a spiral shape along the coil axis. The magnetic core 5 includes a plurality of core magnetic body parts 51 extended to the core axis in parallel and one or more core non-magnetic body parts 52. In the core non-magnetic body part 52, when a conductive rate is lower than that of the core magnetic body parts 51, and the magnetic core 5 is viewed in a cross section vertical to the coil axis, at least two of the plurality of core magnetic body parts 51 are arranged in a direction parallel with the main surface 1u in a sate of being electrically separated by at least one of the one core non-magnetic body parts 52.SELECTED DRAWING: Figure 1 【課題】生じる渦電流を小さくしたインダクタを提供する。【解決手段】インダクタ１０１は、主表面１ｕを有する基板１と、主表面１ｕ上に主表面１ｕと平行なコイル軸に沿って配置された磁気コア５と、前記コイル軸に沿って磁気コア５を螺旋状に取り囲むコイル導体２とを備え、磁気コア５は、前記コイル軸に平行に延在する複数のコア磁性体部５１と１以上のコア非磁性体部５２とを含み、コア非磁性体部５２は、コア磁性体部５１より導電率が低く、磁気コア５を前記コイル軸に垂直な断面で見たとき、前記複数のコア磁性体部５１のうちの少なくとも２つは、前記１以上のコア非磁性体部５２のうちの少なくとも１つによって互いに電気的に離隔した状態で主表面１ｕに平行な向きに並んでいる。【選択図】図１
