Document Type and Number:
Japanese Patent JP6348641
Kind Code:
B2
Abstract:
An electricity storage block includes: an element stacked body in which a plurality of square electricity storage elements 101 is stacked and arranged such that wide surfaces 109W of the adjacent square electricity storage elements 101 are opposed to each other; and a pressing device that presses the element stacked body 11 toward the thermally-conductive sheet arranged on the heat transfer plate. The element stacked body 11 includes holders 160, 170 having wide surface abutment parts 161, 171 in abutment with one of the wide surfaces 109W in a pair in at least the predetermined square electricity storage element 101. The narrow surfaces of the square electrictity storage element is arranged to protrude more towards the thermally conductive sheet than the surface of the holder member by a protrusion length (h1) and the thickness of the thermalyy-conductive member is equal or smaller than h1.
