The present invention relates to a composition for producing an anode for an electricity storage device, wherein the composition comprises an anode active material, a conductive agent, a carbon nanofiber produced by electrospinning a solution containing a carbon fiber precursor, and a binder. The present invention also relates to an anode for an electricity storage device made with the composition, and to an electricity storage device comprising the anode. The composition for producing the anode is characterized in that a portion or the entirety of conventional conductive agents, dispersing agents, and/or binders is replaced by the carbon nanofiber, to thereby significantly improve the specific surface area and electrical conductivity of the anode (i.e. reduce resistance), and thus maximize the efficiency and capacity of the anode active material.
