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 when stacked with each other. Each of the first member and the second member has a stepped face higher than the end face at a position away from a boundary between the stacked first and second members. In the welding step, the boundary between the end faces of the first member and the second member is irradiated with a laser beam in a state that hoods are placed on the stepped faces of the first member and the second member, respectively.
