Provided are a resin composition and shaped product having excellent low-temperature impact resistance, chemical resistance, and tracking resistance, and having rigidity enabling adoption for mechanism components and structures. The resin composition contains (a) a polyphenylene ether resin, and further contains: (b-1) a hydrogenated block copolymer, and/or modified product thereof, having a peak molecular weight of 80,000 to 200,000 and (b-2) a hydrogenated block copolymer, and/or modified product thereof, having a peak molecular weight of at least 10,000 and less than 80,000; and/or (c) an olefinic polymer formed from an olefin other than propylene. The (a) component forms a continuous phase, polymer block B has a glass transition temperature of &#x2212;50&#xb0; C. or lower, the (c) component has a brittleness temperature of &#x2212;50&#xb0; C. or lower, and the composition does not substantially contain (g) polypropylene resin and has a flexural modulus of 1,600 MPa or more as measured in accordance with ISO 178.

Resin composition, method of producing resin composition, and shaped product

Provided is an electric component equipped with a live electrical part and an insulating resin molded article that is molded from a thermoplastic resin composition and is in contact with the live electrical part, wherein: the thermoplastic resin composition includes (A) 60 to 80 parts by mass of a polyphenylene ether resin or a mixture of a polyphenylene ether resin and a styrene resin, (B) 60 to 80 parts by mass of a hydrogenated block copolymer, (C) 5 to 30 parts by mass of a flame retardant, and (D) 0.1 to 3 parts by mass of titanium oxide (in an amount corresponding to 100 parts by mass of the total of (A) to (C)).
