PROBLEM TO BE SOLVED: To provide a lithium ion cell enclosing method capable of providing a moisture proof treatment of high-grade. SOLUTION: For the enclosing method of the cell, housing a cell main body in the cell enclosure composed of a lamination body, comprising at least a base material layer 11, an adhesion layer, a chemical treatment layer, aluminum 12, a chemical treatment layer, an adhesion layer, and a heat seal layer 14, and making the heat sealing layers face each other end tightly sealing a peripheral part including a tub part by heat sealing, the base material layer is made possible to adhere to the heat seal layer, and an extended end part is formed by extending the external end part at one side of the lamination body, and the extended end part is fixed to the outer surface of the other lamination body of the heat seal part by folding.
