A battery comprising a positive electrode; a negative electrode including a negative electrode active material layer that is formed on at least one surface of a negative electrode collector; and an electrolyte, wherein in the negative electrode active material layer from the negative electrode collector up to ½ of a layer thickness in a surface direction of the negative electrode active material layer, a pore volume ratio expressed as (pore volume B/pore volume A) that is a ratio of a pore volume A (ml/g) in a range of 0.001 μm or more and 0.4 μm or less of a pore diameter measured by a mercury porosimeter and a pore volume B (ml/g) in a range of 0.4 μm or more and 10 μm or less of the pore diameter is 1.4 or more and 3.4 or less.
