Abstract

A laser welding method includes a preparation step and a welding step. A first member and a second member prepared in the preparation step have end faces that are adjusted to the same level in height in a state that the first and second members are stacked with each other. The first member has a stepped face lower than its end face at a position away from a boundary between the stacked first and second members. The second member has a stepped face lower than or higher than its end face at a position away from the boundary between the stacked first and second members. In the welding step, the boundary between the end faces of the first and second members is irradiated with a laser beam in a state that hoods are placed on the stepped faces of the first and second members, respectively.
