Disclosed is a polyphenylene ether resin composition containing (A) a polyphenylene ether and (B) one or more members selected from the group consisting of (B-1) polyhedral silsesquioxanes and/or partially cleaved structures of polyhedral silsesquioxanes and (B-2) phosphinates. The component (A) contains a copolymer obtained by polymerizing a phenol containing (a-1) 2,6-dimethylphenol and (a-2) 2,3,6-trimethylphenol. The structural unit composed of (a-1) is contained in an amount of 60-90% by mass and the structural unit composed of (a-2) is contained in an amount of 10-40% by mass, respectively per 100% by mass of the total of the structural units (a-1) and (a-2) in the component (A). |
