Claim:
1. A power storage module comprising a plurality of power storage cells and a plurality of power storage cell holders which the power storage cells and the power storage cell holders are stacked alternately in a stacking direction, a pair of end plates that are superimposed at opposite ends in the stacking direction of the power storage cells and the power storage cell holders, a frame that connects the pair of end plates, an insulator that has an insulating property and covers the frame, and an insulating bus bar plate that has a metal plate electrically connecting the plurality of power storage cells to each other, wherein the power storage cell is covered by a condensation-preventing sheet other than a non-covered portion that corresponds to opposite surface portions which are not covered by the condensation-preventing sheet, and the non-covered portion at one of the opposite surface portions is covered by the power storage cell holder, the insulator, and the bus bar plate, wherein the bus bar plate covers electrodes of the power storage cells, wherein the insulator comprises a plurality of first ribs that extend vertically in a vehicle-mounted state, each of the plurality of first ribs being disposed in parallel on an outer face of the insulator, and wherein the insulator further comprises a plurality of second ribs, each of the plurality of second ribs being connected between two adjacent first ribs.
