Method of manufacturing a coil component

A method of manufacturing a coil component, comprising:

• preparing a wire that includes a linear, central conductor of copper and an insulating coating that covers a circumferential surface of the central conductor;
• preparing a metal terminal that is configured to electrically connect to the central conductor at an end portion of the wire, a plurality of surfaces of the metal terminal being formed of a metal plate of the metal terminal, the metal plate being composed of a copper alloy;
• disposing a tin-containing film on a receiving surface of the plurality of surfaces of the metal terminal, sandwiching the tin-containing film between the central conductor and the receiving surface of the metal terminal, leaving the metal plate exposed on at least one surface of the plurality of surfaces of the metal terminal and disposing at least the end portion of the wire on the tin-containing film;
• and
• welding the central conductor of the wire to the metal terminal by irradiating the tin-containing film with a laser beam with the end portion of the wire disposed along the tin-containing film, wherein during the welding of the central conductor of the wire to the metal terminal, a weld nugget portion is integrally formed by welding the central conductor and a receiving portion and that protrudes from a surface of the receiving portion above which the end portion of the wire is disposed.
