Beschreibung
Zusammenfassung:	Provided is a resin foam that is satisfactorily flexible and highly resistant to heat, exhibits superior strain recoverability at high temperatures, and has a high instantaneous recovery rate. This resin foam is formed from a resin composition containing an acrylic polymer, an active-energy-ray-curable compound having two (meth)acryloyl groups per molecule, an active-energy-ray-curable compound having three or more (meth)acryloyl groups per molecule, and a thermal crosslinking agent. The active-energy-ray-curable compound having two (meth)acryloyl groups per molecule and the active-energy-ray-curable compound having three or more (meth)acryloyl groups per molecule are preferably contained in a total content of from 20 to 150 parts by weight per 100 parts by weight of the acrylic polymer.
