PROBLEM TO BE SOLVED: To improve electric contact properties inside an electrolytic cell and to reduce the production cost of hydrogen/oxygen by reducing the thickness of electrodes of the cell, and also, to improve sealable properties of the cell by using annular plates and an O-ring. SOLUTION: This generator is provided with: an electrode element 6; a first annular plate 7 having a smaller diameter than that of the electrode element 6 and a second annular plate 8 having the same diameter as that of the electrode element 6, which plates are placed on the both side of the electrode element 6; an O-ring 9 fitted to the outer periphery of the first annular plate 7; a gaseous hydrogen flow passage 11a formed in the first annular plate 7; an oxygen flow passage 10a formed in the second annular plate 8 at an angular position (with respect to the cell axis) different from that of the gaseous hydrogen flow passage 11a; a gaseous hydrogen withdrawal path 11 communicated with the gaseous hydrogen flow passage 11a and a gaseous oxygen withdrawal path 10 communicated with the gaseous oxygen flow passage 10a, each of which paths extends through the electrode element 6, first annular plate 7 and second annular plate 8 in the direction of the cell axis at an angular position different from that of the other; and a chamber 10b and another chamber 11b, which are formed in the electrode element 6 and communicated with the gaseous oxygen flow passage 10a each gaseous oxygen withdrawal path 10, and the gaseous hydrogen flow passage 11a and gaseous hydrogen withdrawal path 11, respectively at the time of assembling the electrode element 6, first annular plate 7 and second annular plate 8 in such a way that they overlap each other.
