PROBLEM TO BE SOLVED: To provide a fluororubber-metal laminated gasket material causing no adhesion peel even if used in an electrolyte simultaneously with a different kind of a metal in a practical use environment as a gasket and making it possible to evaluate the retention of sufficient adhesiveness even in a method for confirming and evaluating test solution resistance. SOLUTION: The fluororubber-metal laminated gasket material is constituted by successively laminating a surface treatment agent layer, which contains a zirconium element, a phosphorus element and an aluminum element, a silica-containing resinous vulcanized adhesive layer and a fluororubber layer on a stainless steel sheet. The element mass ratio of zirconium to phosphorus in the surface treatment agent layer is 95:5-60:40 and the element mass ratio of zirconium to aluminum is 90:10-10:90. This fluororubber-metal laminated gasket material causes no adhesion peel even if it is used in an electrolyte such as water, an LLC aqueous solution or the like simultaneously with a metal different from stainless steel in kind such as aluminum, iron or the like in the practical use environment as the gasket.
