Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electroconductive slidable resin molded article excellent in sliding properties and electroconductivity and suitable as a ramp for a hard disk drive and the like. SOLUTION: The molded article is obtained by molding an electroconductive resin composition comprising (A) 50-98.9 wt.% of a thermoplastic resin, (B) 0.1-20 wt.% of a fine carbon fiber having an average fiber diameter of at most 200 nm and a length/diameter ratio of at least 10, and (C) 1-30 wt.% of a lubricating component. The fine carbon fiber has a degree of flex of at least 10° near the surface (0.1-10 μm) of the molded article. COPYRIGHT: (C)2004,JPO
