Wire to conductive metal plate laser welding structure

Abstract

A laser welding structure that is formed by joining a stranded wire (wire) of a signal line and a welding portion (conductive metal plate) by locally applying a laser beam and thereby melting and solidifying the stranded wire of the signal line and the welding portion has the following features. That is, the melting point of the stranded wire of the signal line and the melting point of the welding portion are different. The laser welding structure is obtained by applying a laser beam to one of the stranded wire of the signal line and the welding portion that has a higher melting point, i.e., to the welding portion having a higher melting point.
