PURPOSE:A heat-resistant adhesive, consisting of a polymer having specific repeating units and capable of exhibiting powerful adhesive force without deteriorating heat resistance and keeping a high adhesive force even at high temperatures. CONSTITUTION:An adhesive consisting of a polymer having repeating units expressed by formula I [Y is formula II or III (R is tetrafunctional group selected from the gruop consisting of >=2C aliphatic, cycloaliphatic, monocyclic aromatic, condensed polycyclic aromatic and noncondensed polycyclic aromatic groups in which aromatic groups are mutually linked directly or through crosslinking members)].
