The present invention relates to a to a norbornene-based polymer having a low dielectric constant and low-loss properties, and an insulating material, a printed circuit board and a functional device using the same. More particularly, it relates to a norbornene-based polymer expressed by the following formula (1): wherein, at least one of R1 to R4 is independently substituted or unsubstituted linear C4-C31 arylalkyl or substituted or unsubstituted branched C4-C31 arylalkyl; the rest of R1 to R4 are each and independently H, substituted or unsubstituted linear C1-C3 alkyl, or substituted or unsubstituted branched C1-C3 alkyl; and n is an integer of 250 to 400.
