An object of the present invention is to provide a composition useful for forming an electroconductive resin, the composition comprising a resin and a vapor-growth carbon fiber compounded with the resin, and which can be easily formed into a thin film, and to provide an electroconductive resin which is made from the composition and has various functions such as electromagnetic shielding, electric-filed shielding, electrostatic elimination, and so forth. A polar organic solvent of a film-forming component and a polar organic solvent of a vapor-growth carbon fiber are previously stirred to dissolve and disperse uniformly. The both solutions are mixed and then stirred to provide composition useful for forming electroconductive resin (solution). And the composition useful for forming electroconductive resin is solidified by reaction.
