[PROBLEMS] To provide a heat-shrinkable film and a heat-shrinkable film that are sufficiently shrunk at the mouth and less likely to wrinkle or sink when attached to a container having a large difference between the diameter of the body and the mouth. Providing sex labels. A heat-shrinkable film containing polyester, wherein the dicarboxylic acid component constituting the polyester contains 95 mol% or more of terephthalic acid, the diol component constituting the polyester contains 50 mol% or more of ethylene glycol and cyclohexanedimethanol. Containing 15 mol% or more, when the heat-shrinkable film is immersed in warm water at 70 ° C for 30 seconds, the shrinkage in the main shrinkage direction is 20% or less, and the heat-shrinkable film is immersed in warm water at 80 ° C for 30 seconds The shrinkage rate in the main shrinkage direction is 45 to 65%, and the shrinkage rate in the main shrinkage direction when the heat-shrinkable film is immersed in warm water of 98 ° C. for 30 seconds is 65% or more.
