Abstract:
The invention provides a polyester film including: a polyester substrate; and a layered portion that is disposed on at least one surface of the polyester substrate and has an elastic modulus of from 5 MPa to 800 MPa, a ratio of a peak intensity at 988 cm−1 that is observed by subjecting a surface of the polyester substrate to infrared spectroscopy to a peak intensity at 1410 cm−1 that is observed by subjecting a surface of the polyester substrate to infrared spectroscopy satisfying the following Inequality (I): 0.010≦(peak intensity at 988 cm−1)/(peak intensity at 1410 cm−1)≦0.040 (I).
