A tray for integrated circuits which is made from a thermoplastic resin composition comprising 100 parts by weight of a polyphenylene ether resin, 0.1 to 40 parts by weight of carbon fibers having a number-average fiber length in the range of 0.05 to 1.5 mm, and 0.1 to 50 parts by weight of a flaky inorganic filler having an aspect ratio of 20 or above, and which has a surface resistivity in the range of 10<1> to 10<1><2> OMEGA . This tray is excellent in conductivity and heat resistance and reduced in warpage.
