PROBLEM TO BE SOLVED: To provide a seal structure that is formed by adhering a gasket having sealing function to a base material through an adhesive layer wherein an adhesive layer of a low elastic modulus is used to enable the gasket to lower the inner strain of the gasket and to enlarge the permissible range of the adhesive layer thickness. SOLUTION: In the seal structure produced by adhering a gasket having sealing function to a base material through an adhesive layer, an adhesive layer having a Young modulus of 1 to 50 MPa is used. In this seal structure, when the thickness of the adhesive layer is fixed to a constant value, the inner strain of the gasket decreases by lowering the elastic modulus of the adhesive layer, and the improvement of the quality such as permanency can be attained. On the other side, when the inner strain of the gasket is kept at a constant value, the thickness of the adhesive layer can be increased by lowering the elastic modulus of the adhesive layer, and can enlarge the tolerable range (fluctuation) of the adhesive layer thickness and the cost saving through the simplification of the structure of the adhesion equipment, the maintenance and the like can be expected.
