Abstract
In a laser processing method, a workpiece is set with respect to a jig having a laser passage hole and a relative position of the jig and the workpiece is determined so that the laser passage hole can face toward a target processing point on the workpiece. Then, laser light is irradiated on the target processing point through the laser passage hole while creating a stream of an inert gas flowing from a peripheral area of the target processing point toward the target processing point and flowing away from the workpiece through the laser passage hole.
