Abstract
In an electrochemical device having an element main bodyA enclosed in an exterior packageB, a peripheral region of the exterior packageB is provided with an elastic structure or a plurality of elastic structures R, Rhaving an elastic force in a thickness direction (Z-axis direction) of films. Each of the elastic structures R, Rhas a first region of the exterior packageB folded along a film outer edge, and a second region of the exterior packageB opposed to the first region. Two ends R, R(R, R) of the first region in a direction along the film outer edge are in contact with the second region, and between the two ends R, R(R, R) there is a space (with a maximum height 2R) between the first region and the second region.
