Method for manufacturing coil component

A method for manufacturing a coil component, comprising:

• a step to prepare a drum core that includes a straight winding core, a first flange part provided on one end of the winding core in an axial direction, and a second flange part provided on an other end of the winding core in the axial direction;
• a first winding step where a first conductive wire, being a round wire, is wound around the winding core by a multiple number of turns in a single layer, from the first flange part toward the second flange part, in a manner that adjacent winding segments of the first conductive wire are contacting each other;
• and
• a second winding step where a second conductive wire, being a round wire, is wound around the winding core on an outer periphery of the first conductive wire by a same number of turns as in the first winding step in a single layer, from the first flange part toward the second flange part, in a manner that adjacent winding segments of the second conductive wire are contacting each other;
• wherein, in the second winding step, the second conductive wire is wound around the winding core in a manner that a center of an axial-direction cross-section of the second conductive wire at a second proximate winding segment which is a winding segment at a start of winding closest to the first flange part, is positioned closer to a first flange part side in the axial direction than a center of an axial-direction cross-section of the first conductive wire at a first proximate winding segment which is a winding segment at a start of winding closest to the first flange part in the first winding step, and that a distance in the axial direction, between the center of the cross-section of the first conductive wire at the first proximate winding segment and the center of the cross-section of the second conductive wire at the second proximate winding segment, becomes more than zero but smaller than an equivalent radius of the first conductive wire on the cross-section.
