[PROBLEMS] To selectively produce specific isomers (especially 1,2,3-butanetriol, 1,3-butanediol) among alcohols having 4 carbon atoms (especially butanetriol, butanediol). The method (manufacturing method) which can be provided is provided. In the presence of a catalyst comprising a support and at least one metal selected from the group consisting of iridium, platinum, rhodium, cobalt, palladium, and nickel supported on the support, 1,4-anhydro is obtained. A process for producing a hydrocracked product of 1,4-anhydroerythritol, comprising a step A in which a hydrocracked product of 1,4-anhydroerythritol is produced by a reaction of erythritol and hydrogen.
