<p><P>PROBLEM TO BE SOLVED: To suppress variations in surface pressure of a power storage element due to charging/discharging. <P>SOLUTION: A power storage device comprises: a plurality of power storage elements (1) which are arranged side by side in a predetermined direction (X direction) and each has therein a reaction region (A) where charging/discharging is performed; and restraining mechanisms (20, 30) which sandwich the plurality of power storage elements therebetween in the predetermined direction to restrain the power storage elements. Two power storage elements adjacent in the predetermined direction are arranged to be shifted from each other in a direction perpendicular to the predetermined direction in a state where partial regions (E1) each including one end of the reaction region overlap each other in the predetermined direction. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
