PROBLEM TO BE SOLVED: To provide an acrylic resin film for injection molding co-lamination which excels in shape precision and is hard to cause failure such as wrinkling and breakage, a laminated sheet of its film with another thermoplastic resin, and further an injection molded article on the surface of which the film or the sheet is laminated. SOLUTION: The acrylic resin film is composed of an acrylic resin composition containing rubber particles, and has a tensile strength of≥0.1 MPa, a ratio (S<SB>1</SB>/S<SB>2</SB>) of the tensile strength S<SB>1</SB>to 100% elongation yield strength S<SB>2</SB>of 1-1.5, a tensile yield strength at normal temperatures of≥50 MPa when the tensile strength test is carried out at an ambient temperature of higher than the glass transition temperature of the composition by 10°C, a thickness of 10μm to 500μm. This film gives tensile stress-strain curves as shown in Figures (A) to (D) by the above high-temperature tensile strength test. The laminated film is obtained by laminating another thermoplastic resin layer on one surface of this film, and the injection molded article has this film laminated on its surface.
