摘要：
An anode includes an anode double side coating section; a first anode single-side coating section; and an anode double side non-coating section, the anode double side non-coating section, the first anode single-side coating section, and the anode double side coating section are provided in this order from a first end on the side of spiral winding start of the anode, and in an anode, (“Area density of an anode mixture layer on the first main surface side of the first anode single-side coating section”)/(“Area density of the anode mixture layer on the first main surface side of sections other than the first anode single-side coating section”) is equal to or more than about 1.2.
