Abstract
The present invention aims to provide a resin foam excellent in shock absorption properties and damping properties and less likely to cause sheet misalignment. Provided is a resin foam having a multitude of cells, the resin foam containing: a polyvinyl acetal; and a plasticizer, the resin foam having a loss tangent tan δ with a peak of 0.5 or higher in the range of 0° C. to 50° C. as determined by dynamic viscoelasticity measurement at a measurement frequency of 1 Hz, and the resin foam having a 23° C. compression set of 85% or lower.
