Abstract

A power storage module 11 includes an electrode laminate 12 and a sealing portion 13 made of resin. The sealing portion 13 includes a plurality of sealing layers 30 each including a first region R1 welded to a peripheral portion 21c of a current collector 21 and a second region R2 extending beyond an outer edge 21d of the current collector 21, and a spacer layer 33 provided between the sealing layers 30 adjacent in a lamination direction. The plurality of sealing layers 30 include first sealing layers 31 provided respectively on a second surface 21b of a positive terminal electrode 16 and on a first surface 21a of a negative terminal electrode 17. The first sealing layers 31 each includes a first resin layer 41, a gas barrier resin layer 42, and a second resin layer 43. Outer edge portions of the plurality of sealing layers 30 including a pair of the first sealing layers 31 and an outer edge portion of the spacer layer 33 are integrated with each other by welding to form an end surface welded portion 34. The gas barrier resin layer 42 is provided to overlap with at least the second region R2.
