This heat-shrinkable polyester-based film is characterized in that: the ratio (A1/A2) between the absorbancy (A1) at 1340 cm?1 of the heat-shrinkable polyester-based film measured by the polarized ATR-FTIR method and the absorbancy (A2) at 1410 cm?1 is from 0.65 to 0.9 in the main shrinkage direction of the film and from 0.45 to 0.75 in the direction orthogonal to the main shrinkage direction; and the warm-water heat shrinkage rate for when the film is immersed in 90-degree warm water for 10 seconds is from 40% to 60% in the main shrinkage direction of the film and from 0% to 12% in the direction orthogonal to the main shrinkage direction.
