A polyphenylene ether composition comprising (A) 100 parts by weight of a polyphenylene ether resin or a mixture thereof with a styrene resin, (B) 1 to 40 parts by weight of a flame retardant containing as the main component at least one member selected from the group consisting two specific condensed phosphate esters, (C) 0.3 to 10 parts by weight of a hydrogenated block copolymer prepared by hydrogenating a block copolymer consisting of both one or more styrene polymer blocks, at least one of which has a number−average molecular weight of 15,000 or above, and one or more conjugated diene polymer blocks, and (D) 0.3 to 10 parts by weight of a polyolefin resin with the (C)/(D) weight ratio ranging from 70/30 to 15/85.
