Abstract
A gas separator includes a porous substrate having fine pores opened on its surface and a metal for separating a gas, the porous substrate having fine pores having an average diameter of 0.4-0.9 .mu.m, and the metal for separating a gas being filled into the pores in the porous substrate to close them. A gas separation film seldom exfoliate from the porous substrate, and the gas separator is excellent in durability in comparison with a conventional gas separator.
