Abstract
The present invention provides a method for laser brazing an Al alloy to a steel sheet so as to produce a lap joint member that excels in bonding strength with respect to the Al alloy. The laser brazing method includes a brazing step of forming a brazed part () for bonding an Al alloy () to a hot dip Zn-based alloy coated steel sheet () in which a coating layer () contains 1.0 to 22.0% by mass of Al and a coating weight per surface is 15 to 250 g/m.
