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.

Abstract: Disclosed is a resin material containing a polyolefin, which has a property that discoloration (red to pink), which is considered to be caused by a phenol-based antioxidant, is effectively prevented for a long period of time. The resin material contains two kinds of specific secondary antioxidants represented by the following formulas (I) and (II) added thereto together with a phenol-based antioxidant: wherein R1, R2, R3, R4, R5, R6, R7, and R8 each independently represent a linear or branched hydrocarbon group having 1 to 20 carbon atoms.
