PROBLEM TO BE SOLVED: To stabilize battery characteristics of a nonaqueous electrolyte battery, whose negative electrode active material is a light metal such as lithium by performing a pre-discharge process without contacting a battery with an external terminal. SOLUTION: After a power generation element is accommodated in a battery canister, in the preceding process for sealing that a gasket 3 and a sealing member are disposed at the opening of the battery canister, or in the following process after sealing, a corona discharge electrode 4 is disposed where a positive electrode terminal 2 and a negative electrode terminal 1 are adjacent. By the corona discharge, the positive electrode terminal 2 and the negative electrode terminal 1 are made to be conducted electrically, and pre-discharge is performed.
