PROBLEM TO BE SOLVED: To provide a method for efficiently producing desired 1,3,3,4,4-pentafluorocyclobutene by isomerizing 1,2,3,3,4-pentafluorocyclobutene. SOLUTION: 1,3,3,4,4-Pentafluorocyclobutene represented by chemical formula (2) is produced by isomerization reaction of 1,2,3,3,4-pentafluorocyclobutene represented by chemical formula (1) by using a Lewis acid or a metal fluoride.
