摘要： The present invention addresses the problem of providing an electrically conductive composition which can be used for producing an electric storage device such as a non-aqueous electrolyte secondary battery (e.g., a lithium ion secondary battery) having excellent electric conductivity during an ordinary operation and therefore having excellent battery output properties and the like and also having a function of increasing internal resistance when the internal temperature of the battery is increased, and which enables the production of an electric storage device such as a non-aqueous electrolyte secondary battery having excellent electric conductivity and safety-related functions. The problem can be solved by an electrically conductive composition comprising an electrically conductive carbon material (A), a water-soluble resin (B), water-dispersible resin microparticles (C), an aqueous liquid medium (D), and optionally a water-soluble polyvalent metal compound (E), said composition being characterized in that the water-dispersible resin microparticles contain at least olefin resin microparticles.
