PROBLEM TO BE SOLVED: To provide a method for producing trans-1,3,3,3-tetrafluoropropene by isomerizing cis-1,3,3,3-tetrafluoropropene through an industrially advantageous and efficient process. SOLUTION: The method for producing trans-1,3,3,3-tetrafluoropropene comprises, in a vapor phase, bringing cis-1,3,3,3-tetrafluoropropene into contact with a metal-bearing active carbon bearing a metal oxide or a metal compound or a catalyst obtained by fluorination treatment of such a metal-bearing active carbon.
