Abstract
A module battery comprises a cell including an electrode tab and a cell body having a power generating element hermetically sealed in a package film. The module battery has a constitution in which a plurality of the cells are stacked on one another, and the electrode tabs of the cells adjacent to each other in a stacking direction are interconnected. Further, a bent portion of an approximate L-shape toward the stacking direction of the cells is formed in each of the electrode tabs of the cells, and the bent portions of the cells adjacent to each other in the stacking direction are at least partially overlapped with each other so as to be interconnected.
