PROBLEM TO BE SOLVED: To provide a battery module made more compact. SOLUTION: The battery module is constituted by piling a plurality of flat batteries 1 equipped with a positive pole terminal 14 and a negative pole terminal 16 projecting at a single side of the broad plane S. A pair of the flat batteries 1 form a set and two flat batteries 1 of each set are disposed so that the broad plane S providing the positive pole terminal 14 and negative pole terminal 16 thereon face with each other and that the both terminals are disposed so as not to overlap in the direction vertical to the broad plane S.
