摘要： The present invention addresses the problem of reducing the hardness of a molded article obtained by cross-linking a cross-linking elastomer. The problem addressed by the present invention is solved by cross-linking a cross-linking elastomer composition including at least a cross-linking elastomer and a fluorine oligomer (a) not including hydrogen.
