A prepreg cutting method is provided that cuts prepreg (1) without applying any processing, such as heating, to that part of prepreg other than the place to be cut. When prepreg (1) formed by impregnating a base material with a resin and left to semi-harden is to be cut into a specified dimension, the surface of the prepreg (1) is irradiated with a laser beam (L) so that the resin of the irradiated portion is softened while the laser beam irradiating position is shifted on the prepreg, and the softened resin part is cut by a cutting blade (2). Because the cutting blade (2) cuts the prepreg portion where the resin has softened, resin dust will not scatter. <IMAGE> |
