Zusammenfassung:	PROBLEM TO BE SOLVED: To solve such problems that, since current values inputted/outputted to/from respective batteries have variations in a battery module in which a plurality of batteries are electrically connected in parallel, deterioration states of respective batteries become ununiform, and thereby cycle life characteristics are reduced as the battery module.SOLUTION: A battery module includes a positive electrode external terminal and a negative electrode external terminal connected to each electrode terminal of a plurality of batteries. The batteries are disposed so that electric resistance values of the batteries are reduced as a current path for connecting the positive electrode external terminal and the negative electrode external terminal via the batteries becomes long. Thereby, current values inputted/outputted to/from respective batteries are made uniform.
