Beschreibung
Zusammenfassung:	The present invention addresses the problem of providing a biaxially oriented polyester film for molding which has good moldability, high dimensional stability, high heat resistance and excellent appearance quality after molding and can be molded and appropriately used in various molded members. The biaxially oriented polyester film for molding, wherein: the storage modulus in the film lengthwise direction and the storage modulus in the widthwise direction at 100°C are each 10-1000 MPa inclusive; the storage modulus in the film lengthwise direction and the storage modulus in the widthwise direction at 180°C are each 41-400 MPa inclusive; and the stress at 100% elongation (F100 value) in the film lengthwise direction and the F100 value in the widthwise direction at 150°C are each 5-60 MPa inclusive.
