Abstract
An inductor core includes: a tubular magnetic material body formed of a magnetic material, including pores. The tubular magnetic material body includes an inclined portion including an inclined surface which constitutes a peripheral surface of a truncated cone; and a straight trunk portion which is disposed coaxially with the inclined portion, includes an outer peripheral surface which constitutes a peripheral surface of a cylindrical body, and is connected with the inclined portion. A difference between an average value of distances between centers of gravity of the pores in the inclined portion and an average diameter of the pores in the inclined portion, is smaller than a difference between an average value of distances between centers of gravity of the pores in the straight trunk portion and an average diameter of the pores in the straight trunk portion.
