PROBLEM TO BE SOLVED: To obtain such a foil capsule for isotropic pressurizing treatment that fracture of foils due to strain during the initial deformation can be prevented and a body to be treated in the capsule can be preferentially and selectively deformed, by forming the foil capsule comprising a double-sealed capsule. SOLUTION: A body 3 to be treated such as a ceramic material, metal or resin is housed in metal foils 1, 2 having 30-300μm thickness, and the metal foils 1, 2 are laminated and welded 6 to obtain a sealed capsule 7. Further, another metal foil 8 is laminated and welded 9 on the metal foils 1, 2 which constitute the capsule. In this case, each metal foil 1, 2, 8 has preferably 30-300μm thickness, and moreover, the metal foil 8 is preferably laminated on both outer surfaces of the metal foils 1, 2. |
