摘要： A laser welding joint S1 includes a first bead 10 formed along a first path R1 and a second bead 20 formed along a second path R2. The second bead 20 is formed such that a side portion 20S of the second bead 20 overlaps with a finishing end region 10A of the first bead 10. A starting point of the second path R2 is a position different to a finishing point of the first path R1.
