PROBLEM TO BE SOLVED: To uniformly heat a molding die by effectively introducing heated water vapor into a water vapor chamber, even when the volume of the chamber is large. SOLUTION: The foamed resin molding machine 1 manufactures a foamed resin molded product 6 by filling a foam molding space 5 sectioned by clamping a pair of die parts 4 with raw material resin beads and thermally making the raw material beads foam with water vapor to be supplied into a water vapor chamber 3 arranged communicating with almost the entire face of the die parts 4. In this foamed resin molding machine 1, each of the sections of the water vapor chamber 3 is divided into two or more spaces, and the water vapor is supplied to each of the divided spaces 30 of the water vapor chamber 3. Further, a foaming pressure detection means 8 is arranged in the die parts 4 corresponding to the divided spaces 30 of the water vapor chamber 3. Thus the supply of the water vapor to each of the divided spaces 30 of the water vapor chamber 3 is controlled based on the detection information.
