Common-mode choke coil

A common-mode choke coil comprising:

• a multilayer body including a plurality of non-conductor layers, the plurality of non-conductor layers being stacked and each made of a non-conductor, and the plurality of non-conductor layers including a first plurality of non-conductor layers and a second plurality of non-conductor layers;
• a first coil and a second coil that are incorporated in the multilayer body, the first coil having a first end and a second end which are different ends of the first coil, the second coil having a third end and a fourth end which are different ends of the second coil, the first coil including a first coil conductor disposed along a first interface which is an interface between the first plurality of non-conductor layers, the second coil including a second coil conductor disposed along a second interface which is an interface between the second plurality of non-conductor layers and different from the first interface along which the first coil conductor is disposed, and the first coil conductor and the second coil conductor each having a number of turns of less than 2, at least part of the first coil conductor is curvilinear and at least part of the first coil conductor is positioned outside the second coil conductor, and part of the curvilinear first coil conductor curves toward the second coil conductor, and at least part of the second coil conductor is curvilinear and positioned inside the first coil conductor and part of the curvilinear second coil conductor curves toward the first coil conductor;
• a first terminal electrode and a second terminal electrode that are provided on an outer surface of the multilayer body, the first terminal electrode being electrically connected to the first end, and the second terminal electrode being electrically connected to the second end;
• and
• a third terminal electrode and a fourth terminal electrode that are provided on an outer surface of the multilayer body, the third terminal electrode being electrically connected to the third end, and the fourth terminal electrode being electrically connected to the fourth end.
