Abstract: There are provided a (meth)acrylic resin composition for thermosetting type injection molding comprising a (meth)acrylic monomer (a), a (meth)acrylic polymer (b) and an inorganic filler (c), wherein the spiral flow length is in the range from 400 to 1600 mm; a method for producing the above-described (meth)acrylic resin composition which is BMC, wherein a part or all of the component (b) is used as a thickening agent; and a method for producing a (meth)acrylic resin molded article, wherein a (meth)acrylic resin composition comprising the component (a), component (b) and component (c) is subjected to thermosetting type injection molding. These are useful for producing a (meth)acrylic resin molded article excellent in properties such as appearance, heat resistance, hot water resistance, chemical resistance, dimension stability and damping property.
