Claim 0:
1. An inductor core comprising:
a magnetic main body having a pillar shape and comprised of a magnetic material including pores, wherein
the magnetic main body includes:
an inclined portion including an inclined surface that constitutes 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 includes an outer peripheral surface that constitutes an outer circumferential surface of a cylindrical column body extending from the other end toward the one end, the straight body portion being connected to the inclined portion, and
a difference between an average value of inter-centroid distances between the pores at the straight body portion and an average diameter of the pores at the straight body portion is greater than a difference between an average value of inter-centroid distances between the pores at the inclined portion and an average diameter of the pores at the inclined portion.
