ABSTRACT:
A laser machining method and a laser machining apparatus by which holes excelling in form accuracy can be machined efficiently are to be provided. A first cylindrical lens and/or a second cylindrical lens to correct any deformation of reflective face of a first mirror and/or a second mirror is arranged on an optical axis of a laser beam, and converging positions of the laser beam for an X-component and for a Y-component are coincident with a point on the optical axis.
