ABSTRACT:
An open magnetic circuit multilayer coil component includes a laminate with magnetic layers, a coil, and a nonmagnetic layer provided within the laminate so as to cross a magnetic path formed by energization of the coil. A nonmagnetic material constituting the nonmagnetic layer is a Zn—Cu-based ferrite nonmagnetic material, and a magnetic material constituting the magnetic layer is a magnetic material containing 100 parts by weight of an Ni—Zn—Cu-based magnetic ferrite material and 0.1 to 2.0 parts by weight, in terms of Co3O4, of Co added to the Ni—Zn—Cu-based magnetic ferrite material.
