Japanese Patent JP6577918
Kind Code:
B2
Abstract:
A manufacturing method of a coil component includes: providing an assembly including a wound-wire part formed by winding, around a core, a conductive wire coated with a coating; and a lead part pulled out outwardly from the wound-wire; removing a portion of the coating from the conductive wire at a location outwardly extending away from 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; forming a joining part at an end of the coating-removed lead conductive wire to electrically connect the terminal electrode to the lead part via the joining part by irradiating a laser from the connecting part toward the coating-removed lead conductive wire while restricting an irradiation range of the laser within a range where the coated lead conductive wire is not included.
