It is an object of the present invention to provide a drug container excellent in unsealability, gas barrier property, contamination resistance, heat resistance, antiblocking property and transparency, and to provide a multilayer film for production of the drug container. To achieve the object, the drug container is formed, for example, of a multilayer film including a first layer (1) composed of a linear ethylene/±-olefin copolymer having a density of 0.930 to 0.950 g/cm 3 , a second layer (2) and a fourth layer (4) each composed of a mixture containing a linear ethylene/±-olefin copolymer having a density of 0.860 to 0.920 g/cm 3 and a linear ethylene/±-olefin copolymer having a density of 0. 930 to 0.950 g/cm 3 in a weight ratio of 95:5 to 40:60, a third layer (3) composed of a polycycloolefin, and a fifth layer (5) composed of a mixture containing a polyethylene and a polypropylene, the fifth layer 5 serving as an innermost layer.
