Abstract
When a winding density represents the number of turns of a wire per unit length in a longitudinal direction of a core portion, a plurality of inductor regions having mutually different winding densities of the wire are arrayed in the longitudinal direction of the core portion, and a low-density inductor region with the winding density being relatively low is located between first and second high-density inductor regions with the winding densities being relatively high.
