Abstract
A common mode choke coil includes a multilayer body obtained by stacking insulating layers, first and second coils inside the multilayer body, and first to fourth outer electrodes on outer surfaces of the multilayer body. The first and second outer electrodes are respectively connected to first and second ends of the first coil. The third and fourth outer electrodes are respectively connected to first and second ends of the second coil. The first coil includes first to third spiral conductors connected to one another through via conductors. The second coil includes fourth to sixth spiral conductors connected to one another through via conductors. The first spiral conductor is adjacent to the second and fourth spiral conductors. The fourth spiral conductor is adjacent to the first and fifth spiral conductors. The distance between the first and fourth spiral conductors is smaller than the distances between other spiral conductors.
