PROBLEM TO BE SOLVED: To obtain a multilayer sheet with oil resistance, gas barrier properties and antimarring by laminating a surface layer made up of a specific polyester resin to one or both sides of a base layer of a specifio rubber-modified styrene resin through an adhesive layer. SOLUTION: A polyester resin made up of 80-50wt.% of ethylene glycol and 20-50wt.% of 1,4-cyclohexane methanediol as a dehydric alcohol component and terephthalic acid as an acid component, is laminated to a base material layer of a rubber-modified styrene resin, with rubber dispersed in a particulate diameter of 0.3-1.5μm, which contains 5-15wt.% of styrene.butadiene block rubber made up of 20-50wt.% of styrene unit and 80-50wt.% of butadiene unit as a dispersion phase for 100wt.% of copolymer made up of 30-70wt.% of styrene monomer and 70-30wt.% of alkylester methacrylate monomer as a matrix phase, through an adhesive layer.
