A hydrogenation catalyst and a method for producing 1,3-propanediol using the same are provided. SOLUTION: An alkaline precipitant is added to an aqueous solution containing a copper salt, a manganese salt and a zinc salt to form primary particles in the form of a mixed hydroxide, and then nano-sized colloidal silica is added thereto for aging. CuO (A) MnO 2 (B) ZnO (C) SiO 2 (D) (where A, B, C and D are mass% of components, A is 40 to 85, B Represents a real number of 0.15 to 4, C represents a real number of 0.001 to 2.5, and D represents a real number of 10 to 60, provided that the total amount of B and C is 5 or less.)
