PROBLEM TO BE SOLVED: To manufacture a hollow member for molding which has various cross-sectional shapes, pressure-proof properties, and contraction resistance. SOLUTION: This is a method for producing the hollow member for molding which has a hollow body made of silicone rubber with a fabric 5 embedded and is used for heating/pressurization-molding a hollow fiber-reinforced plastic molding includes a process for molding a fabric-incorporated rubber sheet 43 by holding the fabric 5 between two silicone rubber sheets 33a and 33b, a process of winding the fabric-incorporated rubber sheet 43 onto a core 31, a process of vulcanizing/molding the hollow body by heating/pressurizing the fabric-incorporated rubber sheet 43 wound onto the core 31, and a process of extracting the core 31 form the vulcanized/molded hollow body.
