Abstract
In order to suppress such a situation that polyglyceryl fatty acid ester bleeds out at the time of melting of a thermoplastic resin while improving an impact resistance, a thermoplastic resin composition contains a high impact polystyrene, a calcium carbonate as a filler, and polyglyceryl fatty acid ester as a dispersing agent, and a fatty acid constructing the polyglyceryl fatty acid ester is an unsaturated fatty acid.
