PROBLEM TO BE SOLVED: To provide a method for producing a (Z)-cyanoalkenylcyclopropane carboxylic acid compound from an (E)-cyanoalkenylcyclopropane carboxylic acid compound. SOLUTION: This method for producing the (Z)-cyanoalkenylcyclopropane carboxylic acid compound, comprises a process of isomerizing the (E)-cyanoalkenylcyclopropane carboxylic acid compound (1) to the (Z)-cyanoalkenylcyclopropane carboxylic acid compound (2) [wherein, R<SP>1</SP>is an alkyl or a halogen atom; and R<SP>2</SP>is H, an alkyl or benzyl] in the presence of at least 1 kind of an isomerization catalyst selected from the group consisting of bromine, hydrogen bromide, carboxylic acid bromides, phosphorus bromides, N-bromoimides, N-bromoamides, alkylsilane bromides, thionyl bromides, boron bromides, aluminum bromides, thiols, disulfides, thiocarboxylic acids, nitric acid and nitrate salts.
