<p><P>PROBLEM TO BE SOLVED: To provide a power storage device in which variations in current distribution in a power storage element can be suppressed. <P>SOLUTION: The power storage device has a plurality of power storage elements arranged in a row in one direction, spacers arranged between adjacent power storage elements, and a pressurizing mechanism to apply a pressure in a direction in which the adjacent power storage elements mutually approach. The spacers have a plurality of projections which protrude in the arrangement direction of the plurality of power storage elements and contact the power storage elements. The pressure to act on a second region through the projections in which the current amount becomes smaller than a first region of the storage element is made larger than the pressure to act on the first region through the projections. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
