The present disclosure is to provide an inductor component that can support any high frequency and maintains the strength thereof and that can facilitate reduction of the height and downsizing. The inductor component includes a composite body that includes a plurality of composite layers each including a composite material of an inorganic filler and a resin; and a plurality of spiral wires that each are stacked on the composite layer, the spiral wires each being covered with the other composite layer. The average particle diameter of the inorganic filler is equal to or smaller than 5 [mu]m. The inductor component has an external terminal. The upper end and the lower end of the one side of the wiring, namely the output side, are respectively provided with an external terminal. Only one endof the upper end and the lower end of the other side of the wiring, namely the input side, is provided with an external terminal. 本发明提供一种电感元件，其既能保持强度又能应对高频，并能够实现低矮小型化。电感元件具有：复合体，其多层的复合层构成，该复合层由无机填料以及树脂的复合材料构成；以及多层的螺旋状配线，它们分别层
