The present invention relates to a norbornene polymer that comprises a norbornene monomer having a photoreactive functional group, and a method of manufacturing the same. The norbornene polymer comprises at least 50 mol % of exo isomers among the norbornene monomers having the photoreactive functional group. Since the norbornene polymer according to the present invention comprises at least 50 mol % of exo isomers among the norbornene monomers having the photoreactive functional group, a molecular weight is significantly increased while the yield is not reduced during the manufacturing of the polymer. In views of the three dimensional structure, stability is ensured because the polymer has a planar structure in which the photoreactive groups between the molecules are close to each other. Therefore, the distance between the photoreactive groups is reduced, thus increasing the photoreaction rate.
