PROBLEM TO BE SOLVED: To provide a method for producing a cyanocarboxylic acid by reacting microorganisms with a polynitrile compound of a raw material to provide a reaction mixture of the microorganisms containing the cyanocarboxylic acid of a product, and efficiently separating and purifying the cyanocarboxylic acid by an aqueous system without using an organic solvent by using solid-liquid separation under a mild condition. SOLUTION: The method for producing the cyanocarboxylic acid by reacting the microorganisms with the polynitrile compound comprises (1) a step for carrying out the solid-liquid separation of the cyanocarboxylic acid in a solubilized state in the reaction liquid, and (2) a step for carrying out the solid- liquid separation of the cyanocarboxylic acid in an insolubilized state in the reaction liquid to separate and purify the product.
