Abstract:
1. A laser welding device comprising: a laser beam emitting head directed to a layered bonding position on an end surface in an edge of a layered base material; a first set of rollers for being along one plane of the layered base material; a second set of rollers for being along the other plane opposing the plane; a first member rotatably supporting the first set of rollers and being coupled with the laser beam emitting head; a second member rotatably supporting the second set of rollers and being coupled with the laser beam emitting head; and a pressing means for driving at least one of the first and second members in a direction in which the gap between the first set of rollers and the second set of rollers is reduced in order to sandwich and press the layered base material by means of the first set of rollers and the second set of rollers.
