To press a membrane member against a to-be-pressurized object so that the membrane member adheres to the object without wrinkles, looseness, and the like.SOLUTION: A pressure device comprises: a mounting base on which a to-be-pressurized object can be mounted; a housing arranged so as to face the mounting base, in which a pressure medium chamber can be formed; a medium supply unit that can supply a pressure medium into the pressure medium chamber; and a sheet-fed membrane member arranged so as to cover the to-be-pressurized object between the mounting base and the housing. Also, the pressure device can repeatedly press the to-be-pressurized object through the membrane member using the pressure medium. The membrane member is mounted on one of the mounting base and the housing using a holding tool that includes a frame-shaped first member and a second member which fits into the outer peripheral side of the first member. The holding tool sandwiches a first part in the vicinity of the outer periphery of the membrane member between the first member and the second member. In addition, the holding tool is configured so as to be able to suck a second part, which is on the inner side of the first part, into a groove part arranged on the side-end face contacting to the membrane member of the first member.SELECTED DRAWING: Figure 1A 【課題】膜状部材を皺や弛み等なく被加圧物に圧接させて密着させる。【解決手段】加圧装置は、被加圧物を載置可能な載置基台と、載置基台に対して対向配置されて、内部に圧力媒体室を形成可能なハウジングと、圧力媒体を圧力媒体室内に供給可能な媒体供給部と、載置基台とハウジングとの間に、被加圧物を覆うように配置された枚葉状の膜状部材と、を有し、膜状部材を介して圧力媒体により被加圧物に対して繰り返し加圧可能な加圧装置であって、膜状部材は、枠状の第１部材及び第１部材の外周側に嵌まる第２部材を有する保持治具を介して、載置基台及びハウジングのいずれか一方に取り付けられ、保持治具は、膜状部材の外周部近傍の第１部位を第１部材及び第２部材の間に挟持すると共に、第１部位よりも内側の第２部位を第１部材の膜状部材との接触側端面に設けられた溝部に吸引可能に構成されている。【選択図】図１Ａ
