Provided is a catalyst for reduction reaction with which 1,4-butanediol or tetrahydrofuran can be obtained with higher selectivity than with the related art, using a raw material derived from biomass. The catalyst is used in a reduction reaction of 3,4-dihydroxytetrahydrofuran with hydrogen, wherein the catalyst contains metal catalysts (1) and (2) below; metal catalyst (1): a catalyst containing M1 and M2 below as metal species and supported on a carrier; and metal catalyst (2): a catalyst containing M1 below as a metal species and supported on a carrier; M1: one or more selected from the group consisting of iron and elements belonging to periods 4 to 6 and groups 5 to 7 of the periodic table; and M2: one or more selected from the group consisting of ruthenium, osmium, and elements belonging to periods 4 to 6 and groups 9 to 11 of the periodic table. |
