A nonaqueous electrolytic cell manufacturing method is characterized in that a nonaqueous electrolyte containing vinylene carbonate is used, the initial charge-discharge is carried out under a condition that the negative potential in the completed charged state exceeds the lithium potential by 0.8 V, a coat is formed on the surface of the negative electrode or a coat is formed on the surface of the negative electrode at the initial charge-discharge in such a way at least once, the negative potential is lowered below the lithium potential by 0.4 V.
