The case side wall of the battery case has a tubular portion with a closed cross-section structure consisting of an upper wall, a lower wall, an inner wall, and an outer wall, an inner flange, and an outer flange. A first member made of a steel plate forms an inner flange, an inner wall, an upper wall, an outer wall upper portion, and an outer flange, and a second member made of a steel plate forms an outer flange, an outer wall lower portion, a lower wall, and two reinforcing walls. The reinforcing wall is located in the interior space of the tubular portion at the same height as and below the outer flange. A reinforcing wall is placed at a position facing the shock absorber, increasing the strength of this part, suppressing deformation of the case side wall in a side collision, and suppressing damage to the battery case.
