PROBLEM TO BE SOLVED: To provide a high pressure hydrogen production device where, even if the thickness of a solid polymer electrolytic membrane is reduced by hydrogen pressure, a gap is not formed between the solid polymer electrolytic membrane and a cathode power feeder. SOLUTION: The high pressure hydrogen production device is equipped with: power feeders 3, 4 provided on both the sides of a solid polymer electrolytic membrane 2; separators 5, 6 stacked on the respective power feeders 3, 4; and liquid passages 7, 8. Water is fed to the liquid passage 8, further, the respective power feeders 3, 4 are energized to electrolyze the water, thus high pressure hydrogen gas is obtained in the fluid passage 7. The cathode power feeder 3 made of an elastic material tightly stuck in accordance with the deformation of the solid polymer electrolytic membrane 2 caused by the hydrogen gas pressure and the anode powder feeder 4 whose shape can be retained against the hydrogen gas pressure are provided. The cathode power feeder 3 is deformed by compressive stress, and is tightly stuck to the solid polymer electrolytic membrane 2 caused by the release of the compressive stress. The cathode powder feeder 3 is composed of expand metal made of titanium, a titanium fiber sintered compact or a stacked body of them and a titanium powder sintered compact, and the anode power feeder 4 is composed of a titanium powder sintered compact.
