PROBLEM TO BE SOLVED: To provide a thin and lightweight all solid lithium ion secondary battery.SOLUTION: The all solid lithium ion secondary battery is formed by connecting a plurality of power generating elements A, which is formed by laminating and unifying a positive electrode 1, a solid electrolyte 2 and a negative electrode 3 in order, in series to each other. In the plurality of power generating elements A, the positive electrode 1 of the first power generating element A and the negative electrode 3 of the second power generating element A adjacent to the first power generating element A adhere to each other and are unified by a conductive adhesive 4, which does not have ion conductivity. Since the thickness of the conductive adhesive 4 can be reduced and a metal collector plate used in a conventional one is unnecessary, a thin and lightweight lithium ion secondary battery can be provided. |
