PROBLEM TO BE SOLVED: To provide a battery which prevents the collector lead parts and electrode parts from cansing contact failures or disconnections by preventing displacement and vibration of electrode elements in the battery can and to provide a method for manufacturing the battery. SOLUTION: This gasket 14 comprises pressure parts 14a, 14b which extendi toward the direction of collecting part 10 from the position where a battery can 11 and a battery cover 13 are sealed. When the battery can 11 and the battery cover 13 are sealed by caulking while setting the gasket 14 between them, the presser part 14a is brought into contact with the side face of a presser metal tool 9, and the presser part 14b is brought into contact with the upper face of the collecting part 10 for fixing the presser metal tool 9 and the collecting part 10. Consequently, displacement and vibration of the electrode elements 7 due to vibration and impact from the outside are suppressed and contact failure and disconnection of the collecting leads 8 can be prevented. Moreover, since the electrode elements 7 are fixed simultaneously at the time of caulking, the number of manufacturing processes will not increase especially. |
