1. A supported catalyst comprising a support having a support surface, and supported on the support at least one member selected from the group consisting of heteropolyacids and heteropolyacid salts, wherein 90 mass % or more of the heteropolyacid and/or heteropolyacid salt is present in a surface layer region that extends from the support surface to a distance from the support surface of 30% toward the midpoint in a cross section of the support.
