Abstract
Three or more of n inductors are arranged inside an insulating member. Inside the insulating member, each of the inductors includes coil conductors that are contained in respective coil conductor layers that are stacked in a first direction and via conductors, each of which connects the coil conductors that are contained in the coil conductor layers adjoining in the first direction. Each of the coil conductor layers contains the n coil conductors of the inductors, and a pattern formed of the coil conductors contained in each of the coil conductor layers has n-fold rotational symmetry.
