Abstract
Provided is a laser machining method with which strain occurring in a workpiece can be reduced even when a large number of through-holes are formed. The laser machining method includes: a gas supply step (S) of making a gas pressure on the back surface side of a workpiecehigher than a gas pressure on the front surface side of the workpiecea deep hole machining step (S) of irradiating the workpiecefrom the front surface side with a pulsed laser having a first repetition frequency fthereby forming through-holes A in the workpiece; and a hole finishing step (S) of irradiating the inner surface of the through-holes A with a pulsed laser having a second repetition frequency fthat is lower than the first repetition frequency f
