description PROBLEM TO BE SOLVED: To provide a manufacturing method of an all solid lithium ion secondary battery capable of suppressing consumption of lithium ions due to a side reaction. SOLUTION: After a lithium ion conductive solid electrolyte layer 3 is laminated under pressure on a surface of a positive electrode material 2 composed of a mixture of a positive electrode active material and a lithium ion conductive solid electrolyte, a negative electrode material 4 composed of a mixture of a negative electrode active material and a lithium ion conductive solid electrolyte is laminated on a surface of the electrolyte layer 3. The laminated body is sealed in a bag-shaped container and impressed with a predetermined voltage so that the negative electrode material 4 is pre-doped with lithium ions, and then, the laminated body is taken out from the bag-shaped container to separate the negative electrode material 4, which 4 is laminated on a newly obtained positive electrode material 2 under pressure.
