PROBLEM TO BE SOLVED: To provide an adhesive having excellent adhesion not only at room temperature but also under heating conditions.SOLUTION: The adhesion improving agent (S) is represented by general formula (1). In general formula (1), Xrepresents a residue obtained by removing c active hydrogen atoms from an active-hydrogen-containing compound having a valence of m; c represents an integer satisfying 1≤c≤m; m represents an integer of 1 to 20; Xrepresents a residue obtained by removing one active hydrogen atom from an active-hydrogen-containing compound; Y represents a residue obtained by removing all the carboxyl groups from an aromatic polycarboxylic acid having a trivalence or more; and a represents an integer of 1 or larger, and b represents an integer of 0 or larger. |
