Abstract
Disclosed is a hydrogenated norbornene ring-opened polymer, wherein a proportion of a norbornene-derived repeating unit is 90% by mass or more, a meso diad fraction of the norbornene-derived repeating unit is 80% or more, and in an X-ray diffraction pattern measured at 25° C. using a CuKα radiation source, an X-ray diffraction peak is observed which has a peak top positioned in a diffraction angle (2θ) range of 17° or more and 18° or less.
