Abstract
An example inductor comprises multiple coil parts and each formed by flatwise-winding layers of turns of a flat wire arranged in a radial direction with gaps between each of the layers, and the multiple coil parts are arranged in an axial direction with a clearance. There is provided a clearance between the multiple coil parts, through which air flows, achieving improvement in heat dissipation.
