POWER STORAGE MODULE

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive power storage module which is constructed by arraying a plurality of battery cells.SOLUTION: The power storage module 110 is constructed by arraying the plurality of battery cells 10 whose positive electrode external terminals 30 and negative electrode external terminals 31 have mutually opposite leading out directions and bending directions. The battery cells 10 are arrayed in the state that one side of the battery cells 10 neighboring each other in the arraying direction is rotated by 180° with respect to the battery cell 10 on the other side centering an axis perpendicular to the centers of the array surfaces of the battery cells 10, as a rotational axis. The positive electrode external terminal 30 on one side of the battery cells 10 neighboring each other in the arraying direction and the negative electrode external terminal 31 of the battery cell 10 on the other side are laid one on top of the other and mechanically connected to each other.
