A laminated coil component includes high-magnetic-permeability ferrite layers that are disposed on both main surfaces of a low-magnetic-permeability ferrite layer. Pores or pores filled with a resin are formed in the low-magnetic-permeability ferrite layer. Nickel in the high-magnetic-permeability ferrite layers does not significantly diffuse into the pores or the pores filled with the resin during firing, and thus, Ni does not readily diffuse into the low-magnetic-permeability ferrite layer.
