ABSTRACT:
In a noise filter having a large impedance in a common mode, a first conductor and a second conductor provided on first magnetic sheets and have spiral shapes of plural turns and spaced from each other for avoiding short-circuit. The first conductor is provided inside the spiral shape of the second conductor. The other end of the first inner conductor is located adjacent to the other end of the second inner conductor. The respective other ends of the first inner conductor and the second inner conductor on the magnetic sheet are connected at the respective other ends to first and second conductors provided on another magnetic sheet.
