A conductive composition comprising a vapor grown carbon fiber having an aspect ratio of 40 to 1,000, preferably 65 to 1,000, and a specific surface area or fiber diameter of the fiber within a predetermined range, and a preferable peak intensity ratio (I<SUB>0</SUB>=I<SUB>1360</SUB>/I<SUB>1580</SUB>) of 0.1 to 1, wherein I<SUB>1580 </SUB>represents a peak height at 1,580 cm<SUP>-1 </SUP>and I<SUB>1360 </SUB>represents a peak height at 1,360 cm<SUP>-1 </SUP>in a Raman scattering spectrum; and a resin composition containing the composition; and a production method thereof. The present invention provides: i) a composition which exhibits stable conductivity and less deterioration in physical properties during any molding methods in a conductive plastic in which a conductive filler is dispersed in a polymer; ii) a composite material composition for precision molding which enables production of a molded product with low warpage and is excellent in mechanical properties and performance during the injection molding; and iii) a sliding member composition which exhibits durability under high temperature and heavy load and has a low friction coefficient. |
