Abstract
An inductor core includes a tubular shaped or pillar shaped magnetic main body comprising a magnetic material. The magnetic main body includes: an inclined portion including an inclined surface with an outer circumferential surface of a truncated cone having an outer diameter increasing from one end of the magnetic main body toward the other end; and a straight body portion that is coaxial with the inclined portion and extends from the other end toward the one end, the straight body portion being connected to the inclined portion and including an outer peripheral surface with an outer circumferential surface of a circle tubular body or a cylindrical column body. A skewness Rsk of an outer peripheral surface of the straight body portion located near the inclined portion is smaller than a skewness Rsk of an outer peripheral surface of the straight body portion located near the other end.
