Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate a wrinkle on a corner portion at the time of molding in the case of disposing a design winding forming portion of a patterned sheet for press molding an FRP along a side face of a recess forming protrusion die. SOLUTION: The patterned sheet A for press molding an FRP is obtained by laminating a film 2 on a front surface of a patterned resin-impregnated nonwoven fabric 1 and laminating a sheet material 3 having air permeability on a rear surface of the fabric 1. A design winding forming portion 8 is provided on the sheet A along a side face of a recess forming protrusion die provided at a lower die for installing the sheet A in the case of press molding. A notch 9 is formed only at the film 2 at a corner portion corresponding to a corner for forming the side face adjacent to the protrusion of the portion 8.
