PROBLEM TO BE SOLVED: To obtain a vulcanized rubber elastomer having a low volume resistivity, low dependency of volume resistivity on the environment, and low compression set by vulcanizing a vulcanizable composition containing a halogen- containing polyether-type polymer, a mercaptotriazine compound, an acid acceptor, and a vulcanization accelerator. SOLUTION: The vulcanizable composition contains 100 pts.wt. (A) halogen- containing polyether-type polymer, 0.1-10 pts.wt. (B) mercaptotriazine compound, 0.2-20 pts.wt. (C) acid acceptor, and 0.1-5 pts.wt. (D) vulcanization accelerator. Components A is particularly desirably an epichlorohydrin/ethylene oxide copolymer or an epichlorohydrin/ethylene oxide/allyl glycidyl ether terpolymer. Component D is desirably a thiuram sulfide compound. It is desirable that the vulcanizable composition contains 10-100 pts. wt., per 100 pts. wt. component A, non-conductive filler in addition to components A to D, and it is desirably calcium carbonate.
