PROBLEM TO BE SOLVED: To shorten a temperature lowering process by improving a slowdown of a temperature lowering speed following temperature change of a pressure medium cooled in the temperature lowering process. SOLUTION: The hot isotropic pressure device is provided with a treatment container 2 forming a treatment chamber R, a heat insulating body 3 housing the treatment container 2, a pressure container 4 housing the heat insulating body 3, a cooling unit 5 cooling the pressure container 4, a pressure medium circulating passage 8 communicating an outlet 6 with an inlet 7 of the treatment container 2 to circulate the pressure in the treatment chamber R between the treatment container 2 and the heat insulating body 3, and a pressure medium cooling passage 9 branched off from the pressure medium circulating passage 8. The pressure medium cooling passage 9 is provided with a cooling part 34 between the heat insulating body 3 and the pressure container 4, and a returning part 35 returning the pressure medium having passed through the cooling part 34 to the pressure medium circulating passage 8. A flow applying means for applying a flow promoting cooling with respect the pressure medium communicating through the cooling part 34 is arranged in one of the cooling part 34 or the returning part 35. A returning means for returning the pressure medium having passed through the cooling part 34 to an inlet 7 neighborhood is arranged in the returning part 35. COPYRIGHT: (C)2008,JPO&INPIT
