PROBLEM TO BE SOLVED: To provide an isostatic pressing device capable of shortening the time required to get a target pressure by increasing a pressure rising speed in a low pressure zone. SOLUTION: The isostatic pressing device 1 includes a high pressure container 2, a compressed gas cylinder 5 which supplies a compressed medium gas, a supply piping 6, a first compressor 7, and a second compressor 8. In addition, the isostatic pressing device is equipped with: a high pressure compressing line 15 used when the compressed medium gas sent from the compressed gas cylinder 5 is compressed by the first compressor 7, and further is compressed by the second compressor 8; and a low pressure compressing line 34 used when the compressed medium gas is branched on the upstream side of the first compressor 7, the branched compressed medium gas is sent to the first compressor 7 and second compressor 8, the compressed medium gas compressed by the first compressor 7 is joined to the compressed medium gas compressed by the second compressor 8, and the resulting gas is sent to the high pressure container 2.
