ABSTRACT:
A multilayer body is formed by laminating multiple insulating layers. External electrodes are provided on the opposed side surfaces of the multilayer body and extend in the z axis direction. Coil conductors are laminated together with the insulating layers and form a coil. Coil conductors other than coil conductors connected to the external electrodes are made up of pairs of adjacent coil conductors having an identical shape, and coil conductors forming each pair are connected in parallel to each other. None of the coil conductors connected to the external electrodes is connected in parallel to coil conductors with an identical shape.
