Abstract

A secondary battery module includes: a battery stacked body configured by stacking and placing a plurality of secondary batteries; a pair of end plates that is respectively disposed at one stacked-direction side of the battery stacked body and at another stacked-direction side of the battery stacked body so as to face opposite each other; a pair of side frames that is respectively disposed at one cell-width-direction side and at another cell-width-direction side so as to face opposite each other, a cell width direction being perpendicular to a stacked direction of the battery stacked body; and an elastic body that is placed between an end surface of the battery stacked body on the one stacked-direction side and the end plate on the one stacked-direction side and presses the battery stacked body in the stacked direction. One ends of the side frames on the one cell-width-direction side and the other cell-width-direction side engage with an end plate on the one stacked-direction side and other ends of the side frames engage with an end plate on the other stacked-direction side.
