1. A coil component comprising:
a core including a prism-shaped winding core part, a first flange part that is connected to a first end of the winding core part in an axial direction of the winding core part, and a second flange part that is connected to a second end of the winding core part in the axial direction of the winding core part, and the winding core part has a first side surface, a second side surface that is connected to the first side surface via a first corner, and a third side surface that is connected to the first side surface via a second corner; and
a first wire and a second wire that are wound around the winding core part,
wherein
an overlapping winding region is provided that is a region in which the first wire is wound around the winding core part and the second wire is wound around the winding core part on top of the first wire,
the overlapping winding region includes a prescribed part that is a part in which the first wire and the second wire are wound around the winding core part in such a manner that a gap is interposed between a part of the first wire that is wound along the first side surface and a part of the second wire that is wound along the first side surface, and
an interval between the first wire and the second wire in the prescribed part varies from the first corner to the second corner.
