PROBLEM TO BE SOLVED: To provide a polyester film which can be suitably used for a member such as a film member for a transparent electrode such as a touch panel and a member such as a forming film, which are required to have excellent adhesiveness and slipperiness and to reduce uneven interference due to reflection of outer light after various functional surface layers such as a hard coating layer are formed.SOLUTION: There is provided a laminated polyester film which has a coating film which contains 3 to 70 wt.% of a metal oxide having an average particle diameter of 100 nm or less as a ratio to the whole nonvolatile components in a coating liquid for forming a coating layer and is formed from a coating liquid containing two or more crosslinking agents on one surface of a polyester film and a coating film formed from a coating liquid containing a release agent on another surface, wherein an absolute reflectance of the coating layer surface has one minimum in the wavelength range of 400 to 800 nm and the absolute reflectance at the minimum value is 4.0% or more. |
