    摘要: A thermoplastic resin composition for foam molding including: a component (A) in an amount of 1 to 20 parts by mass; a component (B) in an amount of 0 to 50 parts by mass; an aromatic polycarbonate resin (C) in an amount of 40 to 90 parts by mass; and a high-molecular-weight resin (D) different from the components (A) to (C), having a weight average molecular weight greater than or equal to 2,000,000. When a total of the components (A) to (C) is 100 parts by mass, an amount of the high-molecular-weight resin (D) is 0.1 to 10 parts by mass. Component (A): a rubber-reinforced styrenic resin (A) derived from polymerization, in the presence of a rubbery polymer (a) of a vinyl monomer (b1) including an aromatic vinyl compound; component (B): and a styrenic resin (B) derived from polymerization of a vinyl monomer (b2) including an aromatic vinyl compound.
