A hydrogen separator comprising a porous substrate having a large number of pores communicating from one surface thereof to other surface, and a hydrogen-separating layer disposed on the one surface of the porous substrate in a state that the hydrogen-separating layer has a penetrated portion formed so as to extend through the pores from the one surface to a particular depth, wherein an average pore diameter at the one surface of the porous substrate is 0.02 to 0.5 mum, a thickness of the hydrogen-separating layer is 1 to 5 mum, and a penetration depth of the penetrated portion is 0.05 to 1 mum, is at least equal to the average pore diameter at the one surface of the porous substrate, and is not larger than the half of the thickness of the hydrogen-separating layer. The hydrogen separator hardly generates defects such as cracks, peeling and the like in the hydrogen-separating layer, is superior in durability, and satisfies both of good hydrogen-separating ability and good hydrogen permeability. |
