SECONDARY CELL

A secondary cell includes an electrode body including a plurality of electrode groups each including a plurality of positive electrodes, a plurality of negative electrodes, and at least one separator, the positive electrodes and the negative electrodes each being alternately stacked on each other with the separator interposed in between; and at least one metal plate disposed between the electrode groups. Electrodes that are disposed at both ends of each of the electrode groups are the negative electrodes. The metal plate is in contact with a mixture layer of a negative electrode constituting at least one of the electrode groups, the metal plate being provided in a noncontact state with conductive members other than the mixture layer.
