摘要：
An electrode body includes a stack of a negative electrode plate, a positive electrode plate, and a separator in which the separator is arranged between the negative electrode plate and the positive electrode plate. The positive electrode plate has a positive electrode density of 3.0 g/cm3 or less. The negative electrode plate has a negative electrode density of 1.3 g/cm3 or less. A ratio of a specific surface area of the positive electrode plate to a specific surface area of the negative electrode plate is 0.7 or greater.
