Abstract
A producing device includes an electrolytic bath having chambers partitioned via a cathode side diaphragm and an anode side diaphragm; and a diaphragm protecting structure for preventing damage to the cathode side diaphragm and/or the anode side diaphragm. The electrolytic bath includes a pair of cover members each including a concave portion by which the cathode chamber and the anode chamber are compartmentalized from each other; a partition wall having an opening by which the intermediate chamber is compartmentalized, the partition wall being sandwiched between the cover members via a cathode, an anode, the cathode side diaphragm, and the anode side diaphragm; and seal members, each watertightly closing a gap between the cover member and the partition wall. The diaphragm protecting structure includes protrusions formed to protrude from the seal members into the chambers beyond an edge of the concave portion or an edge of the opening.
