Abstract

One object is to reduce, in a common mode choke coil having three coil conductors, a deviation in stray capacities generated between the coil conductors. A common mode choke coil according to one embodiment of the present invention includes a first coil conductor, a second coil conductor, and a third coil conductor. In said embodiment, the first coil conductor, the second coil conductor, and the third coil conductor extend parallel with each other in a first region in plan view as seen from an axial direction along the coil axis. In said embodiment, in the first region, when seen in a cross section cut along a plane including the coil axis, in an n-th turn, an arranging order of the first coil conductor, the second coil conductor, and the third coil conductor from an inner side in a radial direction thereof is inverted from that in an n+1th turn.
