Provided are a polyester resin composition excellent in adhesiveness, heat-and-moisture resistance, and corrosion resistance without requiring a special device or substrate, and an adhesive composition using the same. The present invention contains the polyester resin (A) and polyisocyanate (B) having a glass transition temperature of 15° C. or less and an ester group concentration of 8500 to 11000 equivalent/10 6 g, satisfying the following (1) to (2) It relates to a polyester resin composition. (1) When a thin film is produced with the polyester resin composition, the storage elastic modulus at 60 degreeC of this thin film is 4.8x10 6 Pa or less. (2) When a thin film is produced from the polyester resin composition, the storage elastic modulus at 200 degreeC of this thin film is 2.0x10 5 Pa or more. |
