PROBLEM TO BE SOLVED: To provide tetracyclododecanedicarbonitriles as raw materials for dicarboxylic acid derivatives capable of introducing an alicyclic skeleton for poly(thio)ester polymers having high heat resistance as well as various physical properties including transparency, low water absorption and optical properties. SOLUTION: The tetracyclododecanedicarbonitriles are tetracyclo[4.4.0.1<SP>2</SP>,<SP>5</SP>.1<SP>7</SP>,<SP>10</SP>]dodecane-3,8-dicarbonitrile of the general formula (I) and tetracyclo[4.4.0.1<SP>2</SP>,<SP>5</SP>.1<SP>7</SP>,<SP>10</SP>]dodecane-3,9-dicarbonitrile of the general formula (II).
