PROBLEM TO BE SOLVED: To provide a manufacture method of a heating cylinder for a molding machine. SOLUTION: In a manufacture method of a heating cylinder with a coating layer 2 of resistance alloy formed in a cylinder inner surface, nests 3, 4 formed out of or coated with a material, to which a hot static pressure water press method can be applied in the same condition to the coating material, are manufactured, a hole is worked in a position serving as a hopper port 5 of the heating cylinder and/(or) a position serving as a tip end part, the nests 3, 4 are inserted in adhesion, a resistance alloy layer is formed by the hot static pressure water press method in a position in an internal periphery of the heating cylinder and serving as the hopper port and/(or) position serving as the tip end part, so as to position the nest in a location necessary for resistance in the hopper port and/(or) the tip end part, the hopper port and/(or) the tip end part is applied with cutting work.
