Abstract
The present invention provides an electrode capable of reducing contact resistance between a resin current collector and the electrode, and a method of manufacturing the electrode. The electrode of the present invention includes a positive electrode current collectorcontaining a polymer material and a conductive filler, a positive electrode active material layerdisposed adjacent to the positive electrode current collector, and a concavoconvex shapecorresponding to a concavoconvex shapeformed on a surface of the positive electrode active material layer that is in contact with the positive electrode current collector, the concavoconvex shape being formed on a surface of the positive electrode current collector that is in contact with the positive electrode active material layer. In the concavoconvex shape in the positive electrode current collector, at least a part of the positive electrode conductive memberthat is in electrical contact with the conductive filler exists in the positive electrode current collector beyond the surface of the positive electrode current collector.
