<P>PROBLEM TO BE SOLVED: To provide a norbornene-based addition polymer applicable to a cooling flow casting film forming process. Ž<P>SOLUTION: The norbornene-based addition polymer includes at least one of a repeating unit represented by general formula (1A), and at least one of a repeating unit represented by general formula (1B), (in the general formula (1A) and in the general formula (1B) R<SP>1</SP>-R<SP>4</SP>each independently represent a hydrogen atom or a substituent, L<SP>1</SP>, L<SP>2</SP>each independently represent a single bond or a divalent linking group, m, p each independently are an integer of 0 or 1, n, q are each independently an integer of 1-4, r, s each independently are an integer of 1-3, in the case r, s are 2 or more, R<SP>1</SP>, R<SP>3</SP>may be same or different, A represents COOR<SP>5</SP>or OCOR<SP>5</SP>, and R<SP>5</SP>represents a substituent).
