A magnetic substrate has such a shape that ridges extending between principal surfaces are cut away by cutout portions. A multilayer body has corners arranged so as to overlap the cutout portions. A coil includes lead portions which are connected with both ends of a coil portion and which are drawn out to the corners. A coil is combined with the coil to constitute a common mode choke coil and includes lead portions which are connected with both ends of a coil portion and which are drawn out to the corners. Connecting portions connect external electrodes to the lead portions and are provided at the cutout portion.

Electronic component and manufacturing method thereof

A composite electronic component includes a multilayer body, coils, an antistatic element and outer electrodes. The multilayer body is configured by laminating insulator layers. The coils are provided on the upper surfaces of the insulator layers. The antistatic element is connected to the coils and includes ground electrodes. The outer electrodes are connected to the coils. The upper surfaces of the insulator layers on which the coils are provided do not intersect with the ground electrodes.

Composite electronic component and composite electronic component manufacturing method

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 FeO, MnO, NiO, ZnO and CuO. The sintered ferrite material has an FeO-reduced content of 25 to 47 mol % and a MnO-reduced content of 1 to 7.5 mol %, or FeO-reduced content of 35 to 45 mol % and a MnO-reduced content of 7.5 to 10 mol %, and a CuO reduced content of 5 mol %.
