PROBLEM TO BE SOLVED: To provide a power storage device capable of securing electrical connection between an uncoated part and a conductive terminal part without welding.SOLUTION: In a secondary battery 10, a positive electrode sheet 21 includes an uncoated part 21c where positive electrode side metallic foil 21a is exposed, and a negative electrode sheet 31 includes an uncoated part 31c where negative electrode side metallic foil 31a is exposed. The positive electrode side uncoated part 21c and the negative electrode side uncoated part 31c are protruding, being mutually separated from a side edge 21d of the uncoated part and a side edge 31d of the uncoated part. The positive electrode side uncoated part 21c includes a part 21f to be sandwiched between the side edge of a negative electrode side active material layer 31b and a positive electrode side conductive terminal part 33a via a separator 19. The negative electrode side uncoated part 31c includes a part 31f to be sandwiched between the side edge 31d of a negative electrode side uncoated part and a negative electrode side conductive terminal part 37a. |
