An inner peripheral end of a first frame shaped sheet of the resin film is positioned outside an outer peripheral end of a cathode, and faces the outer peripheral end of the cathode so as to be separated by a gap. An inner peripheral portion of a second frame shaped sheet is held between the anode and the cathode. A first metal separator facing the first frame shaped sheet is provided with protruding support structure configured to support an inner peripheral portion of the first frame shaped sheet and an outer peripheral portion of the cathode.
