PROBLEM TO BE SOLVED: To provide a polypropylene thermoplastic resin material which improves impact resistance without reducing heat resistance.SOLUTION: The thermoplastic resin material includes: a PP (polypropylene); a PPE (polyphenylene ether); an SEBS (styrene-ethylene-butylene-styrene block copolymer) having a styrene content of 50 to 80 mass%; and a core-shell type rubber which has a shell which consists of acrylic. The thermoplastic resin material has a sea-island structure in which the PP is a sea phase, and the PPE is an island phase. The SP value of the core-shell type rubber is closer to the PPE than the PP. Thus, a large number of core-shell type rubbers are unevenly distributed in the island phase, as compared with the sea phase. |
