摘要： Provided are a two-component curable adhesive that has excellent adhesion force, does not cause coating unevenness in high speed coating, and has a little residual solvent, and a laminate and a package that use the adhesive and have excellent adhesion force and a good appearance. The above problems are solved by a two-component curable adhesive including a polyol component and a polyisocyanate component, in which the polyol component includes a polyether urethane polyol (A) and a polyester polyol (B) having a number average molecular weight of 500 to 3,000, and the content of the polyester polyol (B) is 1.0 to 4.0 parts by mass based on 100 parts by mass of the polyether urethane polyol (A).
