Provided is a catalyst including a metal component including a first component that is rhenium and one or more second components selected from the group consisting of silicon, gallium, germanium, and indium and a carrier on which the metal component is supported, the carrier including an oxide of a metal belonging to Group 4 of the periodic table. Also provided is an alcohol production method in which a carbonyl compound is treated using the above catalyst. It is possible to produce an alcohol by a hydrogenation reaction of a carbonyl compound with high selectivity and high efficiency while reducing side reactions.
