PROBLEM TO BE SOLVED: To provide a pressurizing apparatus that separates pressurizing side from pressurized side, and prevents contamination at a pressure receiving side, using a pressure-transfer medium such as liquid. SOLUTION: A pressurizing apparatus (2) for transmitting pressure to a pressure receiving side by means of a pressure-transfer medium (e.g. water 50) includes a pressurizing side space (46) into which the pressure-transfer medium is housed, a pressure receiving side space (16) that receives pressure, a pressure receiving membrane (34) placed between the pressurizing side space and the pressure receiving side space, and deformable depending on the pressure-transfer medium, a cylinder (70) coupled to the pressurizing side space, and a pressurizing piston (64) for sliding within the cylinder. The movement of the pressurizing piston (64) is transferred by the pressure-transfer medium to the pressure receiving membrane, thus pressuring the pressure receiving side space.
