Abstract

A winding core part includes a two-layer winding region, consisting of a first layer in which a first wire is wound around the winding core part and a second layer in which a second wire is wound around the first layer, and a non-contact winding region in which the first and second wires are wound without contacting each other. The non-contact winding region located is between the first flange part and the two-layer winding region, and the two-layer winding region includes switching parts that are for switching the axial direction positional relationship between turns of the first and second wires in the two-layer winding region and are parts in which the first and second wires cross each other. In the non-contact winding region, the first wire has a longer wire length than the second wire. The first wire has a longer coil length than the second wire through both regions.
