Abstract: An electrically conductive substrate contains at least titanium. An intermediate layer is provided on a primary surface of the electrically conductive substrate. A composite layer is provided on the intermediate layer. The composite layer includes tantalum layers and catalyst layers. Each of the catalyst layers contains platinum and iridium. Each of the tantalum layers is made from tantalum oxide, tantalum, or a mixture of tantalum oxide and tantalum. The tantalum layers and the catalyst layers are alternately stacked one layer by one layer in a thickness direction of the electrically conductive substrate. A bottom layer of the composite layer closest to the primary surface of the electrically conductive substrate is constituted by one tantalum layer of the tantalum layers. A top layer of the composite layer furthest from the electrically conductive substrate is constituted by one catalyst layer of the catalyst layers.

Abstract: An optical member includes a substrate and a thin film that is disposed on the substrate and contains inorganic particles and a resin. The resin has a volume occupancy of less than 5% in a region up to at least 60 nm in depth from a surface of at least a part of the thin film, the surface being opposite from a substrate-end surface of the thin film.

Abstract: An electrolysis electrode includes a conductive substrate, a catalyst layer and a tantalum oxide layer. The conductive substrate includes at least titanium. The catalyst layer is provided on the conductive substrate. The catalyst layer includes platinum and iridium oxide. The tantalum oxide layer is provided on the catalyst layer. In the electrolysis electrode, the catalyst layer is partially exposed.
