PROBLEM TO BE SOLVED: To provide a method for manufacturing a cushion pad having a recessed part inside an extending part to avoid defective molding occurring in the extending part with a thin end. SOLUTION: The method for manufacturing a cushion pad for molding a seat body integrally with a cushion pad P where the extension part P4 extending from an upper side edge in a U shape and a deformed shape part P7 whose cross-sectional thickness is reduced to the end of the extension part are formed is configured to have a step part 11 for forming the deformed shape part P7 in an upper die 10 and a recess forming part 21 for forming a recessed part P8 in the inside P6 of the extension in a middle die 20 and is equipped with the molding process of molding the cushion pad P integrally with the seat body by infusing a raw material after assembling a middle die 20 where the seat body is arranged, the upper die 10, and the lower die 30 to set a die and the demolding process of removing the molded cushion pad P with the seat body from the die.
