Abstract

A laminated coil component that can use inexpensive copper as an internal conductor, and has excellent direct current superimposition characteristics is provided. In a laminated coil component including: a magnetic section including a ferrite material; a non-magnetic section including a non-magnetic ferrite material; and a coiled conductor section containing copper as a main component embedded inside the magnetic section and the non-magnetic section, the non-magnetic section contains at least Fe, Mn and Zn, and optionally Cu. The non-magnetic section has a Fe content of 40.0 mol % to 48.5 mol % in terms of FeO, a Mn content of 0.5 mol % to 9 mol % in terms of MnOand a Cu content of 8 mol % or less in terms of CuO.
