Provided is a hydrogenated ring-opened polymer having excellent ductility. The hydrogenated ring-opened polymer includes 90 mass % or more of norbornene-derived structural units. The proportion of meso diads of cis-structural units (I) of formula (I), shown below, included among the norbornene-derived structural units is not less than 0% and not more than 30% or is not less than 70% and not more than 100%. Trans-structural units (II) of formula (II), shown below, constitute a proportion of not less than 0.5% and not more than 20% among the total of the cis-structural units (I) of formula (I) and the trans-structural units (II) of formula (II).

Hydrogenated ring-opened polymer, resin composition, and shaped product

The present invention is a laminated glass which is prepared by inserting a resin intermediate film between glass plates and adhering the glass plates to integrate them, having a bending deflection at 90&#xb0; C. is 7.3 N/mmor higher, a weight per unit area is 7.5 kg/mor less,
