Beschreibung
Zusammenfassung:	A laser welding method includes: preparing a first member and a second member, the first member and the second member having a first end portion and a second end portion in a first direction, respectively; arranging the second member adjacent to the first member in a second direction intersecting with the first direction such that a distance between the first end portion and the second end portion is 0 or more along the first direction; forming a first molten pool protruding from the first end portion toward at least the second end portion, by emitting laser light to the first end portion; forming a bridging molten pool by emitting laser light to at least the first end portion after the forming of the first molten pool, the bridging molten pool bridging over the first end portion and the second portion; and solidifying the bridging molten pool.
