摘要： PROBLEM TO BE SOLVED: To provide a laser machining apparatus that can form a reverse-tapered through-hole using a simple optical system without using a movable part that is mechanically rotated.SOLUTION: The apparatus sets a first position a, a second position b, and a third position c in this order toward the propagation direction of a laser beam 22 for machining according to the thickness of an object 20 to be machined and an opening diameter of a through-hole 20 to be formed. The outer diameter of the laser beam 22 for machining expands from the first position a to the third position c toward the propagation direction, and the inner diameter of the laser beam 22 for machining expands from the second position b to the third position c toward the propagation direction, so that the outer and inner diameters of the laser beam 22 for machining become maximum at the third position c, and a laser beam is deformed such that an image in circular is formed around the center of a light axis, thereby producing the laser beam 22 for machining. A through-hole 20C is formed on an object 20 to be machined by irradiating the object 20 placed between the first position a and the second position b with the laser beam 22 for machining.
