Provided are: a polyester film having excellent thermal dimensional stability, impact resistance strength characteristics, slipperiness, mechanical properties, transparency, and gas barrier properties; and a film roll obtained by rolling the film. The polyester film is characterized by having: at least one layer which mainly contains a polyester resin comprising a dicarboxylic acid component containing furan dicarboxylic acid as a main component, and a glycol component containing ethylene glycol as a main component; and a layer having a planar orientation coefficient ΔP of 0.005-0.200, a thickness of 1-300 μm, and a shrinkage rate of 3.2% or less in both the MD direction and the TD direction when heated at 150°C for 30 min, and containing at least one additive. |
