摘要： There is provided a common mode choke coil in which a non-magnetic layer and a second magnetic layer stacked on a first magnetic layer and two facing conductive coils are included in the non-magnetic layer, the non-magnetic layer is formed of sintered glass ceramics, the conductive coils and are formed of a conductor containing copper, and at least one of the first magnetic layer and the second magnetic layer is formed of a sintered ferrite material containing Fe2O3, Mn2O3, NiO, ZnO and CuO. The sintered ferrite material has an Fe2O3-reduced content of 25 to 47 mol % and a Mn2O3-reduced content of 1 to 7.5 mol %, or Fe2O3-reduced content of 35 to 45 mol % and a Mn2O3-reduced content of 7.5 to 10 mol %, and a CuO reduced content of 5 mol %.
