Abstract: Disclosed is a hypochlorous acid generating electrode that is substantially free from rhodium, which is comparable in performance to a rhodium-containing electrode and is more durable than the rhodium-containing electrode. The electrode to be used for generating hypochlorous acid by electrolyzing water that contains a chloride ion has excellent hypochlorous acid water generation ability and durability, in which the electrode has an electrode substrate comprising titanium or titanium alloy, and a composite layer that is electrically connected with the electrode substrate and that contains iridium or a compound thereof, tantalum or a compound thereof, and ruthenium or a compound thereof and/or platinum, and does not contain rhodium oxide.
