A method for manufacturing a coil component includes: a first winding step to wind a first conductive wire around a winding core in a single layer from a first flange part toward a second flange part; and a second winding step to wind a second conductive wire around the winding core on the first conductive wire by the same number of turns and in the same direction as in the first winding step in a single layer in a manner that center B of the cross-section of the second conductive wire closest to the first flange part is positioned closer to the first flange part than is center A of the cross-section of the first conductive wire closest to the first flange part, and that the distance in the axial direction, between centers A and B is smaller than the radius of the wire.
