The first layer is interposed between the positive electrode substrate and the second layer. The positive electrode active material layer includes a positive electrode active material, carbon black, and fibrous carbon. A mass fraction of the carbon black in the first layer is higher than a mass fraction of the carbon black in the second layer. A mass fraction of the fibrous carbon in the second layer is higher than a mass fraction of the fibrous carbon in the first layer.
