Methacrylic resin composition

Provided is a methacrylic resin composition in which a methacrylic resin (A) forms a matrix and a rubbery elastomer (B) is dispersed, the methacrylic resin composition having the following characteristics when the total of the methacrylic resin (A) and the rubbery elastomer (B) is taken as 100 mass%. (1) The rubbery elastomer (B) contains polymer particles (b1) having a multilayer structure, polymer particles (b2) having a multilayer structure, and a block copolymer (c). (2) the multilayered polymer particles (b1) have at least one rubber component layer (core part) (b1-1), and have a hard resin component layer (b1-2) on the outermost part (shell part), the number average particle diameter of the rubber component layer closest to the shell part is 0.05 [mu] m or more and less than 0.16 [mu] m, and the content of the multilayered polymer particles (b1) in the resin composition is greater than 7.5 mass% and 42.5 mass% or less. And (3) the multilayer polymer particles (b2) have at least one rubber component laye
