PROBLEM TO BE SOLVED: To obtain a stretched multilayered film excellent in gas barrier properties. SOLUTION: A stretched multilayered film is obtained by stretching a multilayered structure, which is obtained by laminating a layer of a resin compsn. and a polypropylene layer through an adhesive resin layer, by 7-12 times at least in a uniaxial direction. In this case, the resin compsn. comprises two kinds of ethylene/vinyl alcohol copolymers different in m.p. and satisfies 150<=MP (a1)<=172, 162<=MP (a2)<=180 and 4<= MP (a2)-MP (a1)}<=30 [wherein MP (a1) is an m.p. ( deg.C) of an ethylene/vinyl alcohol copolymer measured by a deferential scanning calorimeter(DSC) and MP (a2) is an m.p. ( deg.C) of an ethylene/vinyl alcohol copolymer (a2) measured by a differential scanning calorimeter(DSC)].
