    Abstract: PROBLEM TO BE SOLVED: To provide: an ethylene-propylene-diene rubber foam capable of reducing corrosiveness and improving flexibility; a sealing material having the same; and a method for manufacturing the same.SOLUTION: A rubber composition containing an ethylene-propylene-diene rubber is foamed to obtain the ethylene-propylene-diene rubber foam having a 50% compression load value of 0.1 to 2.0 N/cmand a content proportion of a sulfur atom of ≤1,000 ppm in terms of mass as calculated based on a measurement result by fluorescent X-ray measurement. The sealing material is obtained which has the ethylene-propylene-diene rubber foam, and an adhesive layer provided on at least one surface of the ethylene-propylene-diene rubber foam.
