摘要：PROBLEM TO BE SOLVED: To provide a common-mode coil, in which sputter or the like is unlikely to to enter one winding or the other windings, the rotation in an object device is prevented and one winding and the other winding and a conductor section are welded easily, in the case of a welding or the like, in which the common-mode coil is housed in a housing hole for the object device, and a terminal for the winding and the conductor section for the object device are easily welded. SOLUTION: The common-mode coil contains a cylindrical core body, an insulating bobbin 12, in which the core body is housed, and an insulating cross section 20 crossing the bobbin in the diametrical direction and dividing the bobbin into a pair of semicircular sections. The common-mode coil is composed of a core 10 housed in the housing hole for the object device, and one winding 22 wound on one semicircular section of the bobbin and the other winding 25 wound on the other semicircular section of the bobbin. The common mode coil is further composed of an insulating terminal block 30, with a detent section 34 being engaged with one end and the other end of one winding and one end and the other end of the other winding, while being engaged with the sidewall of the housing hole for the object device.
