PROBLEM TO BE SOLVED: To provide an industrially extremely advantageous method for producing a fluorinated cyclobutene compound without by-producing an isomer. SOLUTION: The method for producing the fluorinated cyclobutene compound represented by general formula (2): C<SB>4</SB>H<SB>m</SB>F<SB>6-m</SB>(m is 0-5) includes reacting a chlorine-containing cyclobutene compound represented by general formula (1): C<SB>4</SB>H<SB>m</SB>Cl<SB>n</SB>F<SB>6-m-n</SB>(m is 0-5; and n is 1-6) with a fluoride salt to substitute the chlorine atoms in the chlorine-containing cyclobutene compound with fluorine atoms. The 1, 3, 3, 4, 4-pentafluorocyclobut-1-ene represented by chemical formula (4) is produced by using 1-chloro-3, 3, 4, 4-tetrafluorocyclobut-1-ene represented by chemical formula (3).
