Claim 0:
1. A manufacturing method of a coil component, comprising:
providing an assembly comprising: a wound-wire part formed by winding, around a core, a conductive wire coated with a coating covering an outer circumference of the conductive wire; and a lead part pulled out outwardly from the wound-wire part and constituted by the coated conductive wire outwardly extending continuously from the wound-wire part, referred to as a coated lead conductive wire, away from the wound-wire part as viewed in an axial direction of the wound-wire part;
removing a portion of the coating from the conductive wire with the coating to form a conductive wire without a coating, referred to as a naked lead conductive wire, at a location further outwardly extending continuously from a remaining portion of the conductive wire with coating, referred to as a coated lead conductive wire, and further away from the wound-wire part than the coated lead conductive wire as viewed in the axial direction of the wound-wire part, wherein an entire coating over an entire circumference of the conductive wire at the portion of the coating is removed;
providing a terminal electrode with a connecting part extending from the terminal electrode;
forming a joining part at a location on an outer side of the lead part at an end of the naked lead conductive wire, and further away from the wound-wire part and the naked lead conductive wire as viewed in the axial direction of the wound-wire part so as to electrically connect the terminal electrode to the lead part via the joining part where a portion of the naked lead conductive wire is fused to and electrically connected to the connecting part by irradiating a laser from the connecting part toward the naked lead conductive wire while restricting an irradiation range of the laser within a range where the coated lead conductive wire is not included.
