Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a laser welding method capable of further excellently welding a first metal plate and a second metal plate of a different plate thickness, without using a filler wire.SOLUTION: An end part of a stainless steel plate S1 and an end part of a stainless steel plate S2 thinner in plate thickness than the stainless steel plate S1, are butted in a joining part, and the stainless steel plate S1 and the stainless steel plate S2 are welded by irradiating a laser beam L to the butted joining part W. The laser beam L having a rectangular irradiation area RA is irradiated to the joining part W from an arrangement of laser diodes for directly emitting the laser beam so that a longitudinal direction of the irradiation area RA becomes parallel to a longitudinal direction of the joining part W.
