PROBLEM TO BE SOLVED: To provide a power-storage module which enables the increase in volume energy density while suppressing the deformation of a case of a power storage device.SOLUTION: A power-storage module comprises rectangular parallelepiped power storage devices 2 connected therein. Each power storage device has a case 2a, and an electrode assembly 2b and an electrolyte 2c which are enclosed in the case 2a. The power storage devices 2 are arrayed along a predetermined array direction (i.e. a direction in which positive and negative electrodes are laminated), and restrained as they are. The case 2a of each power storage device is restrained with a face 2g in contact with the face 2g of adjacent one, provided that the face 2g forms one side of the case 2a. The thickness of the case 2a on the side of the face 2g (especially, at least a part of the case 2a abutting on the adjacent member on the side of the face 2g) is made smaller than the thickness of the case on the side of a face 2h on which the power storage device is not restrained. |
