PROBLEM TO BE SOLVED: To provide a new process for producing 3-(2-cyano-1-propenyl)-2,2-dimethylcyclopropanecarboxylic acid or its salt without using an organophosphorus compound. SOLUTION: The process for producing 3-(2-cyano-1-propenyl)-2,2-dimethylcyclopropanecarboxylic acid or its salt comprises a step of making a 3-formyl-2,2-dimethylcyclopropanecarboxylic acid ester react with propionitrile in the presence of a base.
