PROBLEM TO BE SOLVED: To prepare an adhesive which has excellent storage stability and develops excellent adhesive force on the adhesion of human tooth astylar enamel having high acid resistance to a dental restoring material. SOLUTION: This two-pack type adhesive used for astylar enamels comprises the first liquid compounded with a sulfonic group-containing polymerizable monomer (a) having a methacrylamide group and/or an acrylamide group and the second liquid compounded with an acidic group-containing polymerizable monomer salt (b), wherein water (c) and a water-soluble solvent (d) are compounded in the first liquid and/or the second liquid, respectively, and an adhesion method using the same is also provided. The two-pack type adhesive develops excellent adhesive force for human tooth astylar enamels having high acid resistance, even when a long period passes after produced, because of having excellent storage stability. By the adhesion method, the astylar enamel can simply be adhered to the dental restoring material without giving such a damage as eliminating the gloss of teeth to the teeth or discoloring the teeth.
