Beschreibung
Zusammenfassung:	A problem to be addressed by the present invention is to provide a transparent thermoplastic resin composition having excellent impact resistance and flowability, also having a high transparency and good color tone, and further having good mold deposition. According to the spirit of the present invention, the transparent thermoplastic resin composition includes: 100 parts by mass of a transparent thermoplastic resin composition composed of 10 to 60 parts by mass of a graft copolymer (A) obtained by graft-copolymerizing a monomer mixture (a) containing at least an aromatic vinyl-based monomer (a1) and a (meth)acrylic acid ester-based monomer (a2) in the presence of a rubbery polymer (r), and 40 to 90 parts by mass of a vinyl-based copolymer (B) obtained by copolymerizing a monomer mixture (b) containing at least an aromatic vinyl-based monomer (b1), a (meth)acrylic acid ester-based monomer (b2), and a vinyl cyanide-based monomer (b3); and 15 ppm or more and 40 ppm or less of a polydimethyl siloxane gum (C) having a weight-average molecular weight of 300,000 or more.
