PROBLEM TO BE SOLVED: To provide a hydraulic forming machine capable of reducing the equipment cost. SOLUTION: The hydraulic forming machine comprises molds 30 (31, 35) which are divided and opened into the direction D<SB>1</SB>across the direction in which a stock 10 to be formed is swollen and deformed by the hydraulic pressure, clamping means 40 (41, 46) to apply the clamping force F<SB>1</SB>to the dies 30, and hydraulic pressure applying means 50 (51, 61, 56, 66) to apply the hydraulic pressure inside the stock 10 so as to be swollen and deformed.
