Cell modules (3) are aligned on front and rear sides and left and right sides in a tray (2), and a cross member (11) is disposed to cross inside of the tray (2) in a left-right direction between the front and rear cell modules (3). The cross member (11) is configured to have a hollow shape with a front wall (11e) and a rear wall (11f) coupled with four structure walls (11a to 11d). An upper notch (16) is formed at an upper edge of the cross member (11), and a lower notch (17) is formed at a lower edge, in a state where third and fourth structure walls (11c, 11d) are left. Reinforcements (18) are disposed on both left and right sides of the tray (2), and upper and lower flange portions (18b, 18c) of the left and right reinforcements (18) are joined to outside of side surfaces of the tray (2) on extension lines of the third and fourth structure walls (11c,11d) of the cross member (11), respectively, in the up-down direction, thereby to form load path structures on left and right paths along the cross member (11).
