A secondary battery assembly of the present invention comprises: a secondary battery including a wound electrode body enclosed in a flat rectangular case; a contact member partly contacting a side surface having a maximum area (pressed surface) of outer surfaces of the battery; and a binding member for binding the battery and the contact member, the binding member binding the contact member to partly press against the pressed surface. The contact member includes: a plurality of contact parts arranged discretely, each contact part being in contact with the pressed surface; and a connecting part connecting the contact parts. The contact parts are protruding from the connecting part toward the pressed surface, and to press more strongly both one-side regions of the pressed surface corresponding to portions off the center of the wound body in the winding axis direction, and to press less strongly a central region between the one-side regions.
