PROBLEM TO BE SOLVED: To provide a highly heat-resistant polyimide adhesive exhibiting high adhesion to polyimide resin, and to provide an adhesive sheet using the above adhesive. SOLUTION: This polyimide adhesive, which has a weight-average molecular weight of >=1.0×10<4> and a glass transition temperature of 0-200 deg.C, essentially comprises an acid anhydride component based on an elastomer segment- containing polymer having acid anhydride group and a diamine component based on a 2nd elastomer-containing polymer having amino groups on both ends of the molecule.
