In an open magnetic circuit type laminated coil component having a laminate formed by laminating a magnetic layer and a non-magnetic layer or a low magnetic permeability layer and a coil conductor disposed in the laminate, a zirconium oxide is included in the non-magnetic layer or the low magnetic permeability layer forming the laminate. The content of the zirconium oxide in the low magnetic permeability layer is in the range of about 0.02 wt % to about 1.0 wt %. A zirconium oxide is also included in the magnetic layer in a proportion of less than about 1.0 wt %. As the magnetic layer, a material including Ni-Cu-Zn ferrite as a main component is preferably used. As the non-magnetic layer or the low magnetic permeability layer, a material including Cu-Zn ferrite as a main component is preferably used.
