    Abstract: There is provided a resin foam excellent in dustproof performance, particularly dustproof performance in a dynamic environment. The resin foam of the present invention has 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.
