Zusammenfassung:A positive electrode plate for a non-aqueous electrolyte rechargeable battery includes a positive electrode mixture layer that is formed by a positive electrode mixture including a positive electrode active material and a conductive material. When RS=(RC×BC)/(RA×BA) is satisfied, where RC (mass %) represents a percentage of the conductive material, BC (m2/g) represents a specific surface area of the conductive material, RA (mass %) represents a percentage of the positive electrode active material, BA (m2/g) represents a specific surface area of the positive electrode active material, and RS represents a total surface area ratio, an aspect ratio AR of the conductive material is thirty or greater, the total surface area ratio RS is in a range of 0.20 to 1.93, and a porosity P (%) of the positive electrode mixture layer is in a range of 40% to 55%.
