A multilayer film comprising an upper layer (A), at least one intermediate layer (B), and a lower layer (C) stacked in that order,wherein the intermediate layer (B) comprises a composition (b1) or a composition (b2) below, andthe upper layer (A) and the lower layer (C) each independently comprise an ethylene polymer and/or a propylene polymer:Composition (b1): a composition that comprisesa propylene polymer (p1) having a melting point in the range of 140 to 165°C measured by differential scanning calorimetry and a melt flow rate (MFR； ASTM D 1238, 230°C, 2.16 kg load) in the range of 0.1 to 20 g/10 min,a propylene·α-olefin random copolymer (r1) having a molecular weight distribution in the range of 1.0 to 3.5 determined by gel permeation chromatography (GPC) and a melting point in the range of 90 to 125°C measured by differential scanning calorimetry, and30% by weight to 60% by weight of an ethylene-based elastomer (where the sum of the contents of the propylene polymer (p1), the propylene·α-olefin random copolymer (r1), and the ethylene-based elastomer is 100% by weight)(when the intermediate layer (B) is composed of the composition (b1), the ratio of the content of the propylene polymer (p1) in the entire multilayer film to the sum of the contents of the propylene polymer (p1) and the propylene·α-olefin random copolymer (r1) in the entire multilayer film is 0.1 to 0.35).
