A gasket material, in which a crosslinked rubber layer compounding 30 to 200 parts by weight of titanium oxide based on 100 parts by weight of NBR or hydrogenated NBR is formed on a metal plate, improves blister resistance, and thus exhibits an excellent effect of preventing rubber peeling of the gasket in the engine and leading to an improvement of engine malfunction. Further, the use of NBR or hydrogenated NBR results in an advantage of low cost relative to that of fluororubber. Therefore, the gasket material of the present invention is effectively used as a cylinder head gasket.
