This heat shrinkable multilayer film is provided with a pair of surface layers, and an intermediate layer disposed between the pair of surface layers. Each of the surface layers contains a total of at least 45 parts by weight of one or more thermoplastic resins selected from hydrocarbon-based resins, ethylene-based resins, and propylene-based copolymer resins, but does not contain a cyclic olefin-based resin or contains the same in an amount more than 0 but less than 55 parts by weight. The intermediate layer contains one or more thermoplastic resins selected from hydrocarbon-based resins, ethylene-based resins, and propylene-based copolymer resins, but does not contain a cyclic olefin-based resin or contains a cyclic olefin-based resin at a content ratio less than that of the cyclic olefin-based resin in the surface layers.
