Abstract: The present invention provides a sound insulator which includes: a flexible material (A) having a peak of loss tangent (tan δ), which is determined by dynamic viscoelasticity measurement, in a temperature range of −60° C. to lower than 0° C.; and a resin (B) having a peak of loss tangent (tan δ), which is determined by dynamic viscoelasticity measurement, in a temperature range of 0° C. to 60° C., the sound insulator including the resin (B) at a ratio of 1 to 50 parts by mass with respect to 100 parts by mass of the flexible material (A). The sound insulator of the present invention is a material which realizes excellent sound insulation properties without relying on a complex shape and an increase in weight.

Abstract: An object of the present invention is to provide a novel ethylene/α-olefin/non-conjugated polyene copolymer containing a certain non-conjugated polyene such as VNB as a copolymerization component, having a low long-chain branching content, excellent in cure characteristics in the case of crosslinking by using peroxide, and having good processability. The ethylene/α-olefin/non-conjugated polyene copolymer according to the present invention has constitutional units derived from ethylene (A), an α-olefin (B) having 3 to 20 carbon atoms, and a non-conjugated polyene (C) having a total of two or more partial structures selected from the group consisting of the following general formulas (I) and (II) in a molecule, and satisfies certain requirements.
