PURPOSE:To obtain a battery with a lead body whose mechanical strength is large by irradiating a round rod as the lead body with laser beam and integratedly joining the battery. CONSTITUTION:The side at which the recesses 22 and 23 of a lead body 21 are provided at the lower part of a battery container 1 that corresponds to a negative electrode 2 made of lithic metals and the reverse side are made to contact to each other. Then the recesses 22 and 23 of the lead body 21 are irradiated with laser beam through a lens 26 and the lead body 21 and the battery container 1 are joined at the two locations that correspond to the recesses 22 and 23. As a result, the battery with the lead body that integrates the lead body 21 and the battery container 1 can be obtained. |
