A copper-based catalyst precursor capable of achieving a high conversion ratio and high selectivity in the isomerization reaction of a β,γ-unsaturated alcohol portion and a method for producing the same and to provide a hydrogenation method in which the copper-based catalyst precursor is used are provided. Specifically, a copper-based catalyst precursor obtained by calcining a mixture containing copper, iron, aluminum, and calcium silicate in which an atomic ratio of iron and aluminum to copper [(Fe+Al)/Cu] is in a range of 1.71 to 2.5, an atomic ratio of aluminum to iron [Al/Fe] is in a range of 0.001 to 3.3, and calcium silicate is contained in a range of 15% by mass to 65% by mass at a temperature in a range of 500°C to 1,000°C and a hydrogenation method in which the copper-based catalyst precursor is used are provided.
