FLAT LAMINATED POWER STORAGE DEVICE

PROBLEM TO BE SOLVED: To provide a flat laminated power storage device which can eliminate the possibility of electric short circuit between adjacent cells and easily dissipate heat at low cost. SOLUTION: The flat laminated power storage device includes: cells turned upside down, current collector foil for connecting the positive electrode layers of cells other than a cell disposed farthest to the rear in the arranging direction, to the negative electrode layers of cells adjacent to the cells in the arranging direction; fusion resin provided on a surface of the current collector foil in contact with the cells, between the two cells connected via the current collector foil; top containers and bottom containers for sandwiching the plurality of cells in the vertical direction; a negative terminal connected to the negative electrode layer of a cell disposed closest to the front in the arranging direction; and a positive terminal connected to the positive electrode layer of the cell disposed farthest to the rear in the arranging direction. The top containers and the bottom containers are disposed in gaps between the positive electrode layers and the negative electrode layers which are connected via the current collector foil, and the containers are fixed to the current collector foil with container fusion resin provided on the current collector foil.
