PROBLEM TO BE SOLVED: To provide a non-fogging polyester resin sheet wherein the fog resistance does not decrease over a long period of time, even after the sheet is molded into a form of a vessel through thermoforming. SOLUTION: The sheet is produced by applying an anti-fog additive to a polyester resin sheet wherein the contact angle of waterdrops at the surface is from 45 to 55 deg.. Preferably, the sheet is produced by applying an anti-fog additive to a polyester resin sheet having 300 or more projecting forms per 1×1μm<2> at the surface or by applying an anti-fog additive to a polyester resin sheet having 10 or more grains, observed in a topographic image of an atomic force microscope, per 1×1μm<2> at the surface. |
