Zusammenfassung:	PURPOSE: To provide a conductive thermosetting resin compsn. which gives a molded item having electromagentic shielding properties, flame retardance, a low specific gravity, and high strengths and modulus, enables the wt. reduction more than a conventional compsn., and can give a thin-walled molded item. CONSTITUTION: The compsn. at least contains 20-50wt.% unsatd. polyester resin or vinyl ester resin, 15-50wt.% carbon fibers having lengths of 1-10mm, 5-40wt.% flame-retardant polymer powder nonmeltable at 150 deg.C or lower and having a particle size of 100μm or lower and a specific gravity of 1.5 or lower or flame-retardant polymer fibers having lengths of 1-10mm, and 5-20wt.% flame retardant and is suitable for housings of electric and electronic apparatus such as a notebook computer, a keyboard support, a portable telephone, a headphone stereo cabinet, and a boom box cabinet.
