PROBLEM TO BE SOLVED: To provide a polyester film for a reflection plate which is a polyester film containing calcium carbonate particles and has an excellent reflectance and in which a variation in reflectance within a plane is suppressed.SOLUTION: There is provided a polyester film for a reflection plate which is a polyester film comprising: at least a reflection layer containing calcium carbonate particles and a polyester; and a support layer, in which the density of the reflection layer is 1.20 g/cmor less, the intrinsic viscosity of polyester of the reflection layer is 0.50 g/dL or more and the gas mark of the film is 200 pieces/mor less. |
