Zusammenfassung:An object is to provide a production method that can provide highly pure 2,2'-bis(carboxymethoxy)-1,1'-binaphthyl with good production efficiency. As a solution, a method for producing 2,2'-bis(carboxymethoxy)-1,1'-binaphthyl represented by formula (3) includes a separation step of separating a metal salt of 2,2'-bis(carboxymethoxy)-1,1'-binaphthyl, the metal salt being represented by formula (2), from a reaction mixture by solid-liquid separation. In the method, a 2,2'-bis(alkoxycarbonylmethoxy)-1,1'-binaphthyl represented by formula (1) is used as a starting material.
