Abstract: An ethylene-propylene-diene rubber foamed material is obtained by foaming a rubber composition containing an ethylene-propylene-diene rubber. The ethylene-propylene-diene rubber foamed material has a 50% compressive load value of 0.1 to 2.0 N/cm2 and 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.

Abstract: An ethylene-propylene-diene rubber foamed material is obtained by foaming a rubber composition containing an ethylene-propylene-diene rubber. The ethylene-propylene-diene rubber foamed material has a permanent compression set obtained by being compressed by 50% at 80° C. for 22 hours to be then released at 23° C. after the elapse of 24 hours of 30% or less. 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.
