A laser welding method of the present disclosure includes a first step, a second step, and a third step. In the first step, a first workpiece and a second workpiece are stacked on each other. Each of the first workpiece and the second workpiece has a surface coated with a first material and is made of a second material, which is different from the first material. In the second step, a first region in which the first workpiece and the second workpiece are stacked on each other is irradiated with a laser beam so that the laser beam penetrates both the first workpiece and the second workpiece.
