Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a desired pattern or a metal thin film pattern without cutting a transfer film even in a molded article complicated in design and large in deformation. SOLUTION: A biaxially oriented polyester film satisfies formula (A), Y>=-340X+41940 (X=1.4X2 (X>90) [wherein X is the min. values of th elongations in the axes of a vertical direction (X1), a lateral direction (X2), a 45 deg.-direction (X3) clockwise with respect to the vertical direction (X3) and a 135 deg.-direction (X4) clockwise with respect to the vertical direction and shown by X-Min (X1, X2, X3, X4) and Y is an area calculated from the elongations of the axes of four directions and shown by Y=√2/2(X1X 2+X2X3+X3X4+X4X1)].
