Provided is a method for producing, from a carboxylic acid ester, a corresponding ether. In the method, the reaction product and catalyst can be easily separated, and a large amount of salt waste or hazardous waste is not discharged. The method for producing an ether includes reducing a carboxylic acid ester with molecular hydrogen in the presence of the following Catalyst and producing the corresponding ether, in which the —C(═O)O— group of the carboxylic acid ester has been converted to a —CH2O— group: Catalyst: a catalyst in which the following M1 and M2 are supported as metal species on the following Support. M1: platinum, ruthenium, rhodium, palladium, or iridium. M2: molybdenum, rhenium, tungsten, or vanadium. Support: zirconium oxide, titanium oxide, cerium oxide, or hydroxyapatite.
