PROBLEM TO BE SOLVED: To provide an aluminum integrated gasket capable of sufficiently securing adhesion between aluminum and fluorine rubber vulcanization material without an adhesive, and eliminating process such as metal punching. SOLUTION: The aluminum formed by subjecting aluminum having surface roughness Ra of 3-100μm to an anodic oxidation film treatment and setting the sealing ratio to 40% or less, is directly integrated with the fluorine rubber vulcanization material without an adhesive. The aluminum integrated gasket can sufficiently secure adhesion between aluminum and fluorine rubber vulcanization material without employing process such as metal punching and using an adhesive. The gasket offers an excellent outgas resistance. COPYRIGHT: (C)2004,JPO
