Laser beam processing method and laser processed product

Abstract

There is provided a laser beam processing method in which generation of foreign substances from cut can be suppressed and contamination of a surface of a work can be decreased when performing the processing method using a laser beam on the work made of a polymer material, and a laser processed product. Further, the present invention is to provide a laser beam processing apparatus that is used in the laser beam processing method. The present invention relates to a laser beam processing method for processing the work made of a polymer material using a laser beam, wherein the work is irradiated with a laser beam in a state that the optical axis of the laser beam is tilted in the advancing direction of processing by a prescribed angle with respect to the vertical direction of the work.
