PROBLEM TO BE SOLVED: To provide a laminated type cell that can be continuously laminated and has excellent cell performance by improving an accuracy of position and handleability at the time when a positive electrode and a negative electrode are laminated through a separator to establish an electrode body structure capable of being laminated in a high speed manner and a manufacturing method thereof.SOLUTION: A laminated electrode body E of a laminated type cell comprises a negative electrode -separator pressure-bonded body 4 in which a belt like negative electrode body 31 is pressure-bonded between a pair of separators 2 which continue in a belt shape; and a positive electrode coupling body 5 in which a plurality of positive electrodes 1 are connected each other by a positive electrode lead 1a which continues in a belt shape. The negative electrode-separator pressure-bonded body 4 has folds so that mountain folds and valley folds are alternately disposed between adjacent negative electrodes 3, in the positive electrode coupling body 5, adjacent positive electrodes 1 are alternately inserted into one surface side and other surface side of the negative electrode-separator pressure-bonded body 4, are assembled so as to oppose to a negative electrode 3 where a negative electrode lead 3a is formed, through the separator 2, and are folded with the negative electrode-separator pressure-bonded body 4. |
