Objects of the present invention are to provide a resin composition having good impact resistance, surface smoothness, color developability, and appearance of the molded product, and a method of producing it. Main objects are to provide a resin composition, and a production method for obtaining the resin composition, the resin composition containing a graft copolymer (A) obtained by graft copolymerization of a monomer mixture (a) containing at least an aromatic vinyl monomer (a1) and a vinyl cyanide monomer (a2) in the presence of an acrylic rubber-like polymer (R) obtained by copolymerization of an acrylic acid alkyl ester monomer (r1) and a polyfunctional monomer (r2); and a vinyl copolymer (B) obtained by copolymerization of a monomer mixture (b) containing at least an aromatic vinyl monomer (b1) and a vinyl cyanide monomer (b2), in which the ratio of the total mass of anionic surfactants contained in the resin composition to the total mass of the resin composition is 5,000 ppm (mass/mass) or less; and the ratio of the total of a sulfosuccinic acid compound (E) represented by the following chemical formula [1] and disproportionated rosin (F) contained in the resin composition to the total mass of the resin composition is 2,000 ppm (mass/mass) or less; and the mass ratio of the sulfosuccinic acid compound (E) to the disproportionated rosin (F) is 10:90 to 30:70 (sulfosuccinic acid compound (E): disproportionated rosin (F)): [chem 1] in which R is a C8-22 alkyl or alkenyl group; AO is a C2 or C3 oxyalkylene group; n is an integer from 0 to 20; M and N each independently represent hydrogen, an alkali metal, or an alkaline earth metal; p is 1 when M is hydrogen or an alkali metal, or is 1/2 when M is an alkaline earth metal; and q is 1 when N is hydrogen or an alkali metal, 81 or is 1/2 when N is an alkaline earth metal.
