Abstract

A prepreg sheet attached with a protective sheet is placed on a mounting table to partially overhang. An angle between an edge side direction of an edge section of the mounting table on which overhanging is performed, and a fiber direction of the prepreg sheet, is then set large enough. Overhanging part is physically impacted in a direction to bend fibers of the prepreg sheet to partially peel the protective sheet from the prepreg sheet. A part of the protective sheet peeled from the prepreg sheet is hold and the protective sheet is peeled from an entire surface of the prepreg sheet. A method of peeling a protective sheet from a prepreg sheet more efficiently without damaging the prepreg sheet and an apparatus for peeling to be used therein are provided.
