Abstract: Provided is a two-pack curable adhesive less likely to cause an appearance defect due to air bubbles or the dissolution of a printing layer. A two-pack curable adhesive, containing: a polyisocyanate composition (A) containing a urethane prepolymer (A1), which is a reaction product of polyester polyol (a1), polyether polyol (a2), and a polyisocyanate compound (a3); and a polyol composition (B) containing polyester polyol (B1), in which polyhydric alcohol (a1-2) used in the synthesis of the polyester polyol (a1) and polyhydric alcohol (b1-2) used in the synthesis of the polyester polyol (B1) contain 80% by mass or more of diethylene glycol, respectively, and the compound amount of the polyester polyol (a1) is 50% by mass or more and 90% by mass or less with respect to the total amount of the polyester polyol (a1) and the polyether polyol (a2).
