Claim Text:
1. An electrolytic cell which comprises: a membrane-electrode assembly, which comprises an electrode chamber having at least one opening; a feeder wire-fixing tube fitted to the at least one opening of the electrode chamber of the membrane-electrode assembly; a feeder wire fixed between the at least one opening and the feeder wire-fixing tube, wherein the membrane-electrode assembly comprising at least one rod-form electrode placed in a diaphragm which is preformed into a tube, thereby forming a tubular diaphragm; the tubular diaphragm disposed around the periphery of the rod-form electrode; and a wire-form counter electrode spirally wound around the periphery of the tubular diaphragm, the tubular diaphragm being fixed to the rod-form electrode with the wire-form counter electrode so that the tubular diaphragm is in contact with at least a part of the rod-form electrode and the tubular diaphragm is in contact with at least a part of the wire-form counter electrode to thereby form the electrode chamber, the electrode chamber having a spiral shape and having a gas/liquid passage between the tubular diaphragm and the rod-form electrode, wherein the rod-form electrode is an anode and the counter electrode is cathode, wherein the rod-form electrode comprises diamond, and wherein the wire-form counter electrode is spirally wound at a pitch of 1-10 mm.
