PROBLEM TO BE SOLVED: To provide a production method of a (meth)acrylic resin composition that is excellent in plasticity, and in which a gel colony and a resin foreign matter are very few.SOLUTION: A (meth) acrylic resin composition is obtained by a method in which a block copolymer (B) that includes a polymer block (a) consisting of a (meth)acrylic acid alkyl ester unit, and a polymer block (b) consisting of a conjugated diene compound unit is dissolved into a monomer mixture (A') including at least 50 mass% and less than 100 mass% of methyl methacrylate to obtain a reaction liquid, a moisture content in the reaction liquid is made at most 1,000 ppm, and the monomer mixture (A') is performed by radical polymerization. |
