Abstract

An inductor includes a housing composed of an insulating material and a conical coil provided inside the housing. The conical coil is formed of a spirally wound coil conductor. The winding diameter of the conical coil increases in a continuous manner. The coil conductor has a rectangular cross section. Parts of the coil conductor that are adjacent to each other in a winding axis direction of the conical coil are disposed so as to partially overlap when looking in the winding axis direction of the conical coil. The insulating material of the housing is disposed without any gaps along the periphery of the coil conductor.
