  • Publication number: 20170129231
    Abstract: An embodiment of the present invention provides a laminated polyester film including: a biaxially oriented polyester film which is produced by stretching an un-stretched polyester film in a first direction and stretching the resultant in a second direction perpendicular to the first direction along a film surface and has a small endothermic peak temperature of 160° C. or higher and 210° C. or lower, which is derived from a heat setting temperature measured by differential scanning calorimetry; and an undercoat layer which is formed by applying an undercoat layer forming composition onto one surface of the polyester film stretched in the first direction before being stretched in the second direction, and stretching the resultant in the second direction, and has a modulus of elasticity of 0.7 GPa or higher, a production method thereof, and a solar cell protective sheet and a solar cell module which include the laminated polyester film.
