Abstract
A conductive paste for an electrode mixed material layer has a water content of 1,000 ppm or less. The paste contains a conductive additive, not less than 3 parts by mass and not more than 200 parts by mass of a polymer per 100 parts by mass of the conductive additive, and not less than 12 parts by mass and not more than 350 parts by mass of expandable particles per 100 parts by mass of the conductive additive. The polymer includes at least one functional group selected from the group consisting of a carboxyl group, a hydroxyl group, an amino group, an epoxy group, an oxazoline group, a sulfo group, a nitrile group, an ester group, and an amide group. The expandable particles have an initial thermal decomposition temperature of not lower than 120° C. and not higher than 400° C.
