Abstract: An ethylene-propylene-diene rubber foamed material is obtained by foaming a rubber composition containing an ethylene-propylene-diene rubber. In the ethylene-propylene-diene rubber foamed material, the content ratio of a sulfur atom calculated based on the measurement result of a fluorescent X-ray measurement, based on mass, is 1000 ppm or less, a rate of change of a 50% compressive load value after being heated at 140° C. for 7 days to a 50% compressive load value before being heated is 50% or more and 150% or less, and the 50% compressive load value before being heated is 0.1 N/cm2 or more and 2.0 N/cm2 or less.
