Abstract:
1. A resin foam having a thickness recovery ratio of 65% or more, wherein the thickness recovery ratio is defined as a ratio of a thickness 1 second after releasing a compressed state to an initial thickness, when the resin foam is compressed for 1 minute in the thickness direction so as to give a thickness equal to 20% of the initial thickness in a 23° C. atmosphere; and then the compressed state is released in a 23° C. atmosphere, wherein the resin foam has an average cell diameter of 10 to 180 μm, a repulsive stress at 50% compression of 0.1 to 3.0 N/cm wherein a resin constituting the resin foam includes a thermoplastic resin, and wherein the resin foam has a dynamic dustproofness expressed by less than 100 mm
