Manufacturing method of power storage module and power storage module

A power storage module, comprising:

• an electrode laminate having a plurality of bipolar electrodes, a positive terminal electrode, and a negative terminal electrode;
• a sealing member that seals a pair of electrodes mutually adjacent in the electrode laminate;
• and
• a liquid injection member for supplying an electrolyte solution to the electrode laminate, wherein
• each of the bipolar electrodes has
• a current collector,
• a positive electrode active material layer provided on a positive electrode current collector foil in the current collector, and
• a negative electrode active material layer provided on a negative electrode current collector foil in the current collector,
• the positive terminal electrode has
• a positive electrode current collector foil, and
• a positive electrode active material layer provided on the positive electrode current collector foil,
• the negative terminal electrode has
• a negative electrode current collector foil, and
• a negative electrode active material layer provided on the negative electrode current collector foil,
• each of the positive electrode current collector foils has a positive electrode uncoated portion,
• each of the negative electrode current collector foils has a negative electrode uncoated portion,
• the sealing member seals a space between the positive electrode uncoated portion and the negative electrode uncoated portion in a state where a pressure of the space becomes lower than atmospheric pressure, and
• the liquid injection member communicates the space with outside the sealing member.
