Abstract
A positive electrode for a lithium ion secondary battery, including a positive electrode current collector, a conductive layer which is disposed directly or indirectly on the positive electrode current collector, and which includes a conductive particle, a polymer particle, and a fluororesin or a resin including a structural unit derived from a nitrile group-containing monomer, and a positive electrode active material layer disposed directly or indirectly on the conductive layer, as well as a lithium ion secondary battery using the same.
