PROBLEM TO BE SOLVED: To provide a prepreg cutter blade capable of reducing the cutting load when cutting a prepreg and preventing the fray or crimp of fibers at the cut end section of the prepreg from occurring. SOLUTION: This prepreg cutter blade has a grip section 11, a central section 12, and a tip section 13. The central section 12 has a blade width L gradually expanded in width in the tip direction and a blade thickness W made thicker on the central side in the width direction. The tip section 13 has a blade width L gradually narrowed in width in the tip direction from the central section 12 and a blade thickness W made thicker on the central side in the width direction.
