PROBLEM TO BE SOLVED: To provide a bonding method enabling transfer of a bonded structure within a short time and heating of the bonded structure.SOLUTION: A bonding method comprises: a step of heating a base component and a curing agent, wherein the base component and the curing agent are heated to a temperature equal to or higher than ((melting point M)-10)°C, wherein the base component contains a crystallizing agent with a melting point M and the curing agent contains a crystallizing agent having a polyester skeleton and having carboxyl groups at both ends and a polyether polyol, and wherein the amount of the crystallizing agent having a polyester skeleton and having carboxyl groups at both ends is ≥1 mass% and ≤10 mass% based on the total amount of the polyether polyol and the crystallizing agent having the polyester skeleton and having carboxyl groups at both ends; a mixing step of mixing the base component and the curing agent; a bonded structure forming step of applying a mixed adhesive composition to at least one of a plurality of objects to be bonded and sticking the objects to be bonded to each other so as to form the bonded structure; and a bonded structure heating step of heating the bonded structure. |
