A conductive elastomer composition includes an ionic-conductive elastomer component, which contains an anion-containing salt having a fluoro group (F--) and a sulfonyl group (--SO.sub.2--). The conductive elastomer composition has a volume charge not more than 10.sup.8.5 (.OMEGA.cm) when the volume charge is measured at a voltage of 100V applied thereto in accordance with the method specified in JIS K6911. The conductive elastomer composition has a compression set not more than 30% when the compression set is measured at a temperature of 70.degree. C. for 24 hours at a compressibility ratio of 25% in accordance with "the permanent set testing methods for rubber, vulcanized or thermoplastic" specified in JIS K6262.
