Abstract

A core component is made of a sintered body of an inorganic powder, in which the core component includes a columnar winding portion and a flange portion integrally formed with the winding portion at both axial ends of the winding portion, and a cutting level difference (Rδc) of a roughness curve representing a difference between a cutting level at 25% loading length rate in the roughness curve and a cutting level at 75% loading length rate in the roughness curve of a surface of the winding portion is 0.2 µm or more and 2 µm or less.
