<P>PROBLEM TO BE SOLVED: To provide a power storage device capable of visually recognizing a condition of a binding force applied to a power storage element. <P>SOLUTION: A power storage device (100) has a plurality of power storage elements (10) aligned in a predetermined direction (X-direction), a pair of end plates (40) nipping the plural power storage elements in a predetermined direction, and a plurality of coupling members (50) extending in a predetermined direction, coupling a pair of the end plates, and providing a binding force to the plural power storage elements via the pair of the end plates. Among the plural coupling members, at least one coupling member has marks (S, 62), and a shape of the mark is varied by deformation together with variation of the binding force. <P>COPYRIGHT: (C)2012,JPO&INPIT |
