Claim:
1. A multilayer styrenic resin sheet comprising 10 to 50 stacked layers, each and every layer having an average thickness of 4 to 40 μm and being formed from a styrenic resin composition comprising 35 to 58 mass % of a styrene-conjugated diene block copolymer (A), 33 to 45 mass % of a polystyrene resin (B) and 9 to 20 mass % of a high impact polystyrene resin (C), wherein a peak molecular weight of the styrene blocks of component (A) as measured by GPC is in the range of 30,000 to 120,000, and a half-width of a molecular weight distribution curve of the styrene blocks is in the range of 0.8 to 1.25, a proportion of conjugated diene blocks in 100 mass % of component (A) is 10 to 25 mass %, and each and every layer of the multilayer styrenic resin sheet is formed from substantially the same styrenic resin composition.
