Abstract
A common-mode choke coil includes a loop-shaped core, a cover made of a conductor covering at least part of the core, a first winding wound around an outer surface of the cover, and a second winding wound around the outer surface of the cover. The cover includes a first region around which the first winding is wound, a second region around which the second winding is wound, and two connection regions that connect the first region and the second region to each other in a circumferential direction. The cover has first and second slits in an inner circumferential surface. The first slit extends such that the first region is non-continuous with respect to a winding direction of the first winding. The second slit extends such that the second region is non-continuous with respect to a winding direction of the second winding.
