Claim Text:
1. A common mode choke coil comprising: a core including a winding base extending in an axial direction, the winding base including a first area and a second area; a first wire wound around the winding base; and a second wire wound around the winding base side by side with the first wire; the first area being an area from a first end of a region where the first wire is in contact with the winding base to a first point in the region; the second area does not overlap with the first area and is an area from a second end, which is opposite to the first end, of the region where the first wire is in contact with the winding base to a second point in the region; and when the first wire and the second wire on a same turn are compared with each other, in the first area, the first wire is located nearer the first end, and in the second area, the first wire is located nearer the second end, wherein the core further includes flanges provided on both sides of the winding base in the axial direction; each of the first wire and the second wire is connected to electrodes provided on respective surfaces of the flanges on a first side in an orthogonal direction orthogonal to the axial direction; the first wire and the second wire make a same number of turns; the number of turns of the first wire and the second wire is an even number; the first wire and the second wire cross each other on a surface of the winding base on the first side in the orthogonal direction.
