Summary:PURPOSE: A spontaneously winding adhesive film is provided to facilitate recovery by being transformed into a pipe-like form when heated, and to enable stable peeling by spontaneously winding in a smooth manner owing to a uniform peeling stress. CONSTITUTION: A spontaneously winding adhesive film (1) comprises a multi-layer substrate including a heat-shrinkable film (2), an adhesive layer (3), and a separator. The arithmetic mean roughness of the surface of the adhesive layer after separator peeling is below 10 micron. The arithmetic mean roughness of the release surface of the separator is below 10 micron. The peeling force of the separator is below 1.0 N/50 mm. The shrinkage of the heat-shrinkable film in a main shrinking direction is 30% to 90% at a temperature of 70°C to 180°C. The multi-layer substrate includes a rigid film (4) of which Young's modulus multiplied by the thickness is below 3.0×10^5 N/m.
