PROBLEM TO BE SOLVED: To provide an adhesive for forming an adhesive pattern which has a good pattern shape and is capable of bonding adherends together with sufficient adhesive strength, and to provide a method for producing a bonded product and a method for forming an adhesive pattern using the adhesive.SOLUTION: The method for producing a bonded product in which a first adherend and a second adherend are bonded together via an adhesive pattern comprises the steps of: providing, on the first adherend, an adhesive layer comprising an adhesive containing a polyimide compound obtained by reacting an acid anhydride, which contains 30 mol% or more of a tetracarboxylic acid dianhydride represented by general formula (I) based on the total amount of the acid anhydride, with diamine; etching a predetermined portion of the adhesive layer with an etchant containing water, an alkaline compound, and a nucleophilic agent or a hydrazine-based etchant to form an adhesive pattern; and bonding the second adherend to the adhesive pattern. In the formula (I), n represents an integer of 2-20. |
