PROBLEM TO BE SOLVED: To provide molded articles obtained by molding a rubber modified styrenic polymer which excels in transparency and, simultaneously, impact strength and moldability. SOLUTION: The molded articles are obtained by molding a rubber modified styrenic polymer obtained by polymerizing styrene, a (meth)acrylic ester, and a copolymerizable monomer in the presence of a rubbery elastomer which is (a) a styrene/butadiene block copolymer composed of 30-50% styrene and 70-50% butadiene and having (b) a weight average molecular weight of the styrene block of 60, 000-75, 000 and (c) a molecular weight of the peal portion of the GPC chromatogram of the styrene block of 68,000-74,000 and, at the same time, has an average particle diameter of 0.2-0.8μm, and the rubber modified styrenic polymer comprising 1-15 pts. rubbery elastomer and 99-85 pts. sum of 35-75% styrenic units, 65-25% (meth)acrylic ester monomer units, and 0-20% copolymerizable monomer units.
