Abstract
An aromatic polysulfone resin composition comprising 100 parts by weight of an aromatic polysulfone resin, 3 to 15 parts by weight of an electro-conductive carbon black having a dibutyl phthalate absorption of 150 ml/100 g or more and 0.1 to 2.5 parts by weight of a fluorocarbon-type surface active agent. The aromatic polyslfone resin composition has surface resistivity in a range of 10.sup.7 to 10.sup.13 .OMEGA., remarkably lowered initial charged voltage and half-life period, and excellent thermal stability and dimensional accuracy, so that it is suitable for use as a material for electronic parts, office automation equipment parts and audiovisual equipment parts.
