PROBLEM TO BE SOLVED: To provide a transparent polyester film for vapor deposition which stably develops high gas barrier property and markedly improved moisture-proof performance even when a thin film is vapor-deposited thereon and to provide a transparent vapor-deposited polyester film. SOLUTION: The transparent polyester film for vapor deposition and the transparent vapor-deposited polyester film each comprises a biaxially oriented polyester film characterized in that it satisfies a thickness of 5 to 100μm, a surface oligomer content of 20 mg/m<SP>2</SP>or lower, a film melting subpeak temperature Ts of 190 to 235°C, and a film diethylene glycol content of 2.0 wt.% or lower.
