The production method involves thermal decomposition of a carbon source at 800 to 1,300° C. in the presence of, as a catalyst, a transition metal compound having a vapor pressure of 0.13 kPa (1 mmHg) or more at 150° C. and spraying of the carbon source and the transition metal compound in gas form toward the reactor inner wall to allow reaction to proceed. The vapor grown carbon fiber having a larger aspect ratio has excellent dispersibility, and when added in a resin, a smaller amount contributes to enhancement in electroconductivity and thermal conductivity, as compared with a case using conventional one.
