A method for laser brazing a bonding target sheet that is stacked on a sheet surface of a hot dip Zn-based alloy coated steel sheet, a coating layer of the hot dip Zn-based alloy coated steel sheet containing 1.0% by mass to 22.0% by mass of Al, and the bonding target sheet being an Al sheet or an Al alloy sheet, the method comprising: - a brazing step of forming a brazed part on the sheet surface for joining the bonding target sheet and the hot dip Zn-based alloy coated steel sheet together, wherein: - a coating weight on the sheet surface of the hot dip Zn-based alloy coated steel sheet being 15 g/m 2 to 250 g/m 2, - in the brazing step: - the brazed part being formed by emitting a laser beam toward a brazing filler metal so as to melt the brazing filler metal, while arranging the brazing filler metal such that the brazing filler metal abuts on an end surface of the bonding target sheet and a distance d (mm) between the brazing filler metal and the sheet surface satisfies Formula below: 0.2 ≤ d ≤ t and - the brazed part being formed such that, in a cross section of the brazed part taken along a plane orthogonal to a direction in which the brazed part extends, a bead width of the brazed part on the sheet surface satisfies Formula below: t ≤ W ≤ 4 t where W: bead width (mm) of the brazed part, and t: sheet thickness (mm) of the bonding target sheet. - a brazing step of forming a brazed part on the sheet surface for joining the bonding target sheet and the hot dip Zn-based alloy coated steel sheet together, - a coating weight on the sheet surface of the hot dip Zn-based alloy coated steel sheet being 15 g/m 2 to 250 g/m 2, - in the brazing step: - the brazed part being formed by emitting a laser beam toward a brazing filler metal so as to melt the brazing filler metal, while arranging the brazing filler metal such that the brazing filler metal abuts on an end surface of the bonding target sheet and a distance d (mm) between the brazing filler metal and the sheet surface satisfies Formula below: 0.2 ≤ d ≤ t and - the brazed part being formed such that, in a cross section of the brazed part taken along a plane orthogonal to a direction in which the brazed part extends, a bead width of the brazed part on the sheet surface satisfies Formula below: t ≤ W ≤ 4 t where W: bead width (mm) of the brazed part, and t: sheet thickness (mm) of the bonding target sheet. - the brazed part being formed by emitting a laser beam toward a brazing filler metal so as to melt the brazing filler metal, while arranging the brazing filler metal such that the brazing filler metal abuts on an end surface of the bonding target sheet and a distance d (mm) between the brazing filler metal and the sheet surface satisfies Formula below: 0.2 ≤ d ≤ t and - the brazed part being formed such that, in a cross section of the brazed part taken along a plane orthogonal to a direction in which the brazed part extends, a bead width of the brazed part on the sheet surface satisfies Formula below: t ≤ W ≤ 4 t where W: bead width (mm) of the brazed part, and t: sheet thickness (mm) of the bonding target sheet.
