The purpose of the present invention is to provide a method in which a readily industrially available olefin containing chlorine and fluorine is used to simply and efficiently produce a separate olefin containing chlorine and fluorine by olefin metathesis under mild conditions. The present invention relates to a method for producing at least one type of compound selected from the group consisting of the olefin compounds represented by formulas (51) and (52) by reacting the olefin compound represented by formula (21) with the olefin compound represented by formula (31) under the presence of at least one metal catalyst selected from the group consisting of the compounds represented by formulas (11) to (15).
