Abstract
A laminated sheet with a cover material, an adhesive cover tape, and an electronic component packaging container molded. A laminated sheet having a surface layer on both sides of a substrate layer, and the substrate layer includes 30 to 70 mass % of a component mentioned below, 70 to 30 mass % of a component mentioned below, and 0 to 30 mass % of a recycled material of the laminated sheet to the total mass of the substrate layer. The component is a rubber modified (meth)acrylic acid ester-vinyl aromatic hydrocarbon copolymer having a conjugated diene rubber component content of 5 to 15 mass %. The component is a vinyl aromatic hydrocarbon-conjugated diene block copolymer containing 15 to 30 mass % of monomeric units derived from conjugated dienes. The component is at least one polymer selected from the group consisting of a vinyl aromatic hydrocarbon polymer and a rubber modified vinyl aromatic hydrocarbon polymer.
