To provide a hot isotropic pressure device capable of automatically stopping gas supply to the inside of a high-pressure container at an appropriate time only by setting target pressure and a target temperature.
After the gas supply by a pressurizing means is stopped (S8), when a temperature in a heating region of the high-pressure container reaches a preset target temperature by heating by a heating means (S9-S12), the hot isotropic pressure device sets beforehand conditions related to the pressure and the temperature when the gas supply by the pressurizing means is stopped based on the target pressure and target temperature so as to achieve preset target pressure in the high-pressure container (S4). After at least gas supply by the pressurizing means is started (S5), on the condition that the detected pressure and the detected temperature satisfy the stop conditions set in Step S4 (Yes side in S7), gas supply by the pressurizing means is automatically stopped (S8).
