    • PROBLEM TO BE SOLVED: To diminish the generation of a membrane flaw (break) by forming a hydrogen selective permeation membrane and a columnal structural membrane, each of which has a specific thickness on a sheet-like base with a surface flatness and burning or peeling the base. SOLUTION: A hydrogen permeable membrane 8 which is comprised of a Pd-Ag alloy and has a membrane pressure of 0.1-20 μm is formed on a polyethylene film sheet as a base 6 by a vacuum vapor deposition process. In addition, on the hydrogen permeable membrane 8, a columnal Ni structural membrane with a membrane pressure of 40-300 μm such as Co is formed using the vacuum vapor deposition process to create a composite membrane made up of the base 6, the hydrogen permeable membrane 8 and the columnal structural membrane 7. The base 6 of polyethylene film is burned by heating the composite membrane at about 550 deg.C or higher under an atmospheric pressure at a heating furnace. Consequently, a hydrogen permeable membrane composite material made up of the hydrogen permeable membrane 8 and the columnal structural membrane 7 is obtained. The columnal structural membrane 7 possibly breaks when it is 40 μm or less thick. Therefore, the required thickness is preferably 40 μm or more. On the other hand, from the viewpoint of pressure loss, the thickness if preferably 300 μm or less.
