PROBLEM TO BE SOLVED: To enhance productivity of a power storage device by applying effective technique to the power storage device pouring an electrolyte into an outer packaging film. SOLUTION: The power storage device 10 has a unit housing part 11a for housing a three-electrode laminating unit (an electrode unit) 17; an upper side part 11c positioning in the upper part of the unit housing part 11a in electrolyte pouring; a side part 11e positioning in the side of the unit housing part in electrolyte pouring; and a storage part 11b positioning between the unit housing part 11a and a lower side part 11d, formed in a laminate film (an outer packaging film) 11, and after the lower side part 11d and the side part 11e are sealed, an electrolyte is poured from the upper side part 11c, the electrolyte is stored in the storage part 11b in the lower part of the thee-electrode laminating unit 17, and then the upper side part 11c is sealed, thereby, air can be removed from the laminate film 11 without overflow of the electrolyte. Productivity of the power storage device 10 can be thus enhanced. COPYRIGHT: (C)2009,JPO&INPIT
