ELECTRICITY STORAGE MODULE

An electricity storage module (10A, 10B) includes an electricity storage element group (12) in which a plurality of electricity storage elements (11) are electrically connected, and a positive-electrode and a negative-electrode power terminals (22P, 22N, 66P, 66N) to be electrically connected to the electricity storage element group (12) and electrically connected to mating terminals (14). The power terminals (22P, 22N, 66P, 66N) are selected from a positive-electrode and a negative-electrode vertical power terminals (66P, 66N) to which the mating terminals (14) are connected in a vertical downward direction or a positive-electrode and a negative-electrode non-vertical power terminals (22P, 22N) to which the mating terminals (14) are connected in a direction different from the vertical downward direction.
