A resin material including a hydrogenated crystalline polar group-containing dicyclopentadiene ring-opening polymer and a hydrogenated crystalline non-polar dicyclopentadiene ring-opening polymer in a weight ratio (hydrogenated crystalline polar group-containing dicyclopentadiene ring-opening polymer:hydrogenated crystalline non-polar dicyclopentadiene ring-opening polymer) of 100:0 to 1:99, the hydrogenated crystalline polar group-containing dicyclopentadiene ring-opening polymer being obtained by melt-mixing a hydrogenated crystalline non-polar dicyclopentadiene ring-opening polymer, a radical initiator, and a polar group-containing compound that includes an ethylenically unsaturated bond, the resin material including a structural unit derived from the polar group-containing compound that includes an ethylenically unsaturated bond in a ratio of 0.05 to 3.0 parts by weight based on 100 parts by weight of the hydrogenated crystalline polar group-containing dicyclopentadiene ring-opening polymer and the hydrogenated crystalline non-polar dicyclopentadiene ring-opening polymer in total; and a resin film including the resin material; and a laminate film including the resin film.
