Upon dispersing fine carbon fibers into water, by using an anionic surfactant having a high electrostatic repulsion effect, an nonionic surfactant having a high stereoscopic repulsion effect, and an anionic surfactant having high electrostatic and stereoscopic repulsion effects, in combination, an aqueous dispersion of fine carbon fibers which shows a high dispersibility without causing significant cohesion of mutual fine carbon fibers, and maintains a mean particle diameter (d
