An isostatic press is provided to make it possible to treat a workpiece at a stable temperature accuracy by heating both pressure medium and a pressure vessel efficiently. An isostatic press(1) comprises: a heat insulator(3) that forms a treatment chamber(R) which contains a workpiece(W); a pressure vessel(2) that covers the heat insulator; a heating unit(4) that heats the pressure vessel; and a pressure medium supplying device(5) that can supply pressure medium into the pressure vessel, wherein a pressure medium introducing space(S) connected to the treatment chamber, and can introduce the pressure medium is provided between the heat insulator and the pressure vessel, wherein the pressure medium introducing space is in communication with the treatment chamber through a communication hole(15a) formed in a top part of the heat insulator, and wherein the pressure medium supplying device is connected to the pressure medium introducing space through a pressure medium introducing port(18) formed on a bottom part of the pressure vessel.
