Zusammenfassung:	A polyester film according to an embodiment includes a polyester resin. The polyester resin includes a repeating unit having a cyclohexane skeleton and a repeating unit having a benzene ring. The polyester film has a base peak which is a peak related to bending vibration of the benzene ring and a first peak which is a peak related to C-O stretching vibration in a spectrum measured using a Fourier transform infrared spectrometer (FT-IR). The base peak is a peak at a wavenumber of 788 cm-1 to 798 cm-1. The first peak is a peak at a wavenumber of 1129 cm-1 to 1139 cm-1. The intensity of the base peak and the intensity of the first peak differ by -0.05 to +0.05.
