Abstract
A laser welding method according to this disclosure is a laser welding method for welding first and second coils (members) to each other by applying a laser beam to the first and second coils in a state where the first and second coils are brought into contact with each other. The laser welding method includes: a first step of forming a weld pool by applying a laser beam to the first coil; and a second step of continuing the application of the laser beam to the first coil until the width of a bridge formed between the first and second coils becomes wider than the width of the laser beam, the bridge being formed such that the weld pool is attached to the second coil by growing.
