发明名称 積層型インダクタおよび電源回路モジュール
摘要 A multilayer inductor includes a multilayer body formed by stacking magnetic layers on top of one another. Loop-like line-shaped conductors are respectively formed on the magnetic layers. The loop-like line-shaped conductors are connected to one another by interlayer connection conductors, and thereby a coil conductor having an axis extending in the stacking direction is formed. One end of the line-shaped conductor, which is an uppermost-layer-side end portion of the coil conductor, is connected to a line-shaped conductor, which is for routing and is formed on a higher layer, by a interlayer connection conductor. The line-shaped conductor is connected to an interlayer connection conductor that is formed so as to penetrate through substantially the center inside the loop-like line-shaped conductors. The interlayer connection conductor is connected to an external connection conductor on a bottom surface of the multilayer body via a line-shaped conductor and an interlayer connection conductor.
