Abstract: The present invention provides a heat-shrinkable multilayer film that has excellent wear resistance and that suffers less from static electricity generation and surface stickiness. Also provided are a method for manufacturing the heat-shrinkable multilayer film and a heat-shrinkable label formed using the heat-shrinkable multilayer film. The present invention is directed to a heat-shrinkable multilayer film including, in order: a wear-resistant layer (A) containing a polyester resin (a), a (meth)acrylic resin, a hydrocarbon wax, and an antistatic agent; a front layer (B) containing a polyester resin (b); an intermediate layer (C) containing a polystyrene resin; and a back layer (D) containing a polyester resin (d), the wear-resistant layer (A) containing the hydrocarbon wax in an amount of 1 to 60 parts by weight and the antistatic agent in an amount of 0.1 to 10.0 parts by weight, per 100 parts by weight of the total of the polyester resin (a) and the (meth)acrylic resin.
