Abstract

This invention relates to a conductive paste for lithium-ion battery positive electrodes and a mixture paste for a lithium ion battery positive electrode that have an easy-to-apply viscosity, even when a relatively small amount of a dispersion resin is incorporated. More specifically, the invention provides a conductive paste for lithium-ion battery positive electrodes, the conductive paste comprising a dispersion resin (A), conductive carbon (B), and a solvent (C), the dispersion resin (A) containing a resin (A1), the resin (A1) containing, as one constituent component, a polymerizable unsaturated group-containing monomer (A1-1) represented by a specific formula.
