Patent ID: 8759679

Claim:
A laser welding structure formed by joining a wire and a conductive metal plate by locally applying a laser beam and thereby melting and solidifying both the wire and the conductive metal plate, wherein a melting point of the wire and a melting point of the conductive metal plate are different from each other, the laser beam is applied to one of the wire and the conductive metal plate that has a higher melting point, the melting point of the conductive metal plate is higher than the melting point of the wire, before the melting, the conductive metal plate has a wide shape so that the wire is concealed behind the conductive metal plate as viewed in an irradiation direction of the laser beam, and the conductive metal plate has a first surface facing to the wire and a second surface which is a surface opposite to the first surface, and the laser beam is applied to the second surface.
