摘要： PROBLEM TO BE SOLVED: To provide a rubber composition for diaphragm attaining a reliable bonding between a diaphragm rubber and a metal only with an adhesive without using a primer which is conventionally understood as indispensable, while maintaining desired preferable rubber characteristics required by diaphragm, and consequently having possibility of reducing cost. SOLUTION: The rubber composition used for bonding with a metal member (20) comprises a hydrogenated nitrile rubber (HNBR) having a middle high to high acrylonitrile content of 31-42 wt.%, sulfur and an organic peroxide used as vulcanizing agents, and an ester plasticizer, wherein the peroxide used as the vulcanizing agent is an α,α'-bis(tert-butylperoxy)-diisopropylbenzene and the ester plasticizer is an adipic acid ester.
