The inductor wiring includes a plurality of wiring portions arrayed in a direction perpendicular to the first main surface. The element body includes a plurality of interlayer insulating layers filling spaces between the wiring portions that are adjacent to each other in a direction perpendicular to the first main surface. The interlayer insulating layers each contain an insulating base material and a plurality of filler particles dispersed within the base material. In a first interlayer insulating layer, which is one of the plurality of interlayer insulating layers, the average particle size of the filler particles is less than or equal to the standard deviation of the thickness of the first interlayer insulating layer.
