A coil component includes a winding core, and a first wire and a second wire that are spirally wound around the winding core, that have substantially the same number of turns, that are not electrically connected to each other, and that have a twisted portion at which the first wire and the second wire are twisted together. In the coil component, the first wire and the second wire are wound around the winding core such that layers are formed. The twist pitch of the twisted portion at a turn in a first layer differs from the twist pitch of the twisted portion at a turn adjacent thereto in a second layer.
