PROBLEM TO BE SOLVED: To provide a methacrylic resin composition which has high transparency, is excellent in flowability and heat resistance, and has little variations in impact resistance.SOLUTION: A methacrylic resin composition contains a predetermined methacrylic resin (A) and an acrylic rubbery polymer (B) having a predetermined average particle diameter by predetermined amounts, and satisfies the following (I) to (III) conditions: (I) a weight average molecular weight is 40,000 to 300,000; (II) in a differential molecular weight distribution curve obtained by a GPC elution curve, an area of an area having a molecular weight of 15,000 to 30,000 is 10-70% with respect to the total area ratio obtained by the differential molecular weight distribution curve; (III) when arbitrary 10 visual fields of the methacrylic resin composition are observed at a magnification of 50,000 times using a transmission electron microscope, the visual fields contain a specific number of specific rubbery polymers.SELECTED DRAWING: Figure 3 |
