Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an acrylic resin film excellent in thermal shrinkability.SOLUTION: A methacrylic resin composition is made from acrylic ester crosslinked elastic body particles and a methacrylate ester polymer. Using the composition, the acrylic resin film excellent in thermal shrinkability, formability and workability can be obtained by specifying the amount of copolymerization of polyfunctional monomers in the acrylic ester crosslinked elastic body particles, the weight average molecular weight of methyl ethyl ketone soluble contents of the methacrylic resin composition, and the content of the crosslinked elastic body particles and by specifying the die slip aperture and the die temperature in extrusion molding.
