PROBLEM TO BE SOLVED: To provide an exo-norbornene monomer from which a norbornene-based polymer usable as an excellent electronic material, optical material or the like can be produced in good yield. SOLUTION: The production method involves reacting an endo-norbornenecarboxylic acid ester with a basic catalyst to isomerize the endo-isomer to the exo-norbornene monocarboxylic acid ester. As the basic catalyst, a metal alkoxide is preferably used. COPYRIGHT: (C)2008,JPO&INPIT
