SOUND INSULATOR
The present invention provides a sound insulator which includes: a flexible material (A) having a peak of loss tangent (tan ´), 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 ´), 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.
