1. A hydrogen separation apparatus comprising:

  • a porous support member;

    an independent hydrogen permeable membrane disposed above the porous support member, the independent hydrogen permeable membrane being planar and different from a coating film; and

    a joining member for joining the porous support member and the independent hydrogen permeable membrane, the joining member being independent from the independent hydrogen permeable membrane and fixedly disposed to the porous support member and being formed of at least one selected from the group consisting of palladium, silver, palladium-silver, copper and palladium-copper,wherein the joining member includes a plurality of joining members disposed to the porous support member, wherein the joining members are disposed separate from each other by a certain distance in a direction parallel with an interface between the porous support member and the independent hydrogen permeable membrane,wherein the independent hydrogen permeable membrane has a substantially uniform thickness hmp.wherein the certain distance is 200 ttmhor smaller,wherein the joining member has a thickness equivalent to or more than a pore diameter of the porous support member at an interface of the porous support member and the independent hydrogen permeable membrane in a direction of a normal line of the interface between the porous support member and the independent hydrogen permeable membrane,wherein the independent hydrogen permeable membrane is singly treatable before the joining member joins the porous support member and the independent hydrogen permeable membrane,wherein the porous member is provided with a protective layer disposed at a Surface side opposite to the independent hydrogen permeable membrane, andwherein the porous support member and the protective layer exist on a same plane, which is parallel to the interface between the porous support member and the independent hydrogen permeable membrane.
