Abstract

Provided are a polyester film and a method of manufacturing the polyester film. A polyester film has a base film and at least one image receiving layer which is disposed on at least one surface of the base film, the base film contains a polyester and titanium oxide particles, the mass-based content of the titanium oxide particles in the base film satisfies Formula 1 on the assumption that the thickness of the base film is T μm, a surface roughness standard deviation Rq is 0.01 μm to 0.12 μm, a cross section in a thickness direction orthogonal to a plane direction of the base film has voids whose average area per void is 0.01 μm/void to 0.10 μm/void, and a surface roughness standard deviation Rq of an outermost surface of the image receiving layer is 0.01 μm to 0.1 μm.
