PROBLEM TO BE SOLVED: To provide a blow molding die which can control the temperature of a work. SOLUTION: This blow molding die is of such a type that a plate-like work W can be blow-molded by the fluid pressure of air, and also, is composed of a top force 31 and a bottom force 21 between which the edge part of the work W is inserted, a support plate 25 for supporting the lower surface of the work W, a diffusion plate 24 for controlling the temperature of the support plate 25, and an air supply device 23 for supplying air to the bottom force 21 through an air supply aperture 211 formed in the bottom force 21. The diffusion plate 24 is installed between the support plate 25 and the air supply aperture 211, and controls the flow of air to be supplied from the air supply aperture 211.
