To obtain a heat-shrinkable film which has low natural shrinkage in preservation, high shrinkage in heating, low density, excellent hygiene and excellent sebum whitening properties.

The resin composition comprises (A) >90 wt.% and ≤98 wt.% of a resin having an alicyclic structure in the molecule and (B) ≥2 wt.% and <10 wt.% of a polyethylene-based resin having ≤0.92 g/cm3 density and ≥2 g/10 minutes MFR (190°C, 2.16 kg load). The heat-shrinkable film is obtained by forming a film using the composition and stretching the film. The heat-shrinkable film is obtained by stretching a laminated film equipped with the resin composition on the outermost layer.
