摘要： The present invention addresses the problem of providing a natural rubber-containing thermoplastic resin composition which uses a natural rubber latex and has physical properties achieving excellent balance among impact resistance, fluidity and color tone, without requiring a complicated deproteinization process for natural rubbers. A solution of the problem is a natural rubber-containing thermoplastic resin composition which contains a graft copolymer (A) that is obtained by graft polymerizing a vinyl monomer mixture (a), which contains at least an aromatic vinyl monomer, to a rubber polymer (R) that is formed of 10-70% by mass of a natural rubber having a weight average particle diameter within the range of 0.3-1.2 [mu]m and 30-90% by mass of a synthetic rubber having a weight average particle diameter within the range of 0.2-0.4 [mu]m. This natural rubber-containing thermoplastic resin composition is characterized in that: the natural rubber particles contain natural rubber particles having particle diameters of 1.0 [mu]m or more in an amount of 5% by mass or more; and the inner graft rate of the rubber polymer (R) particles having particle diameters of 1.0 [mu]m or more is 20% or more.
