PURPOSE:To enable mass production of a thin battery with excellent liquid leakageproofness which has a thickness of less than 1mm by providing a package member consisting of plastic or rubber in the sealing sections of negative and positive cans and sealing it by means of ultrasonic deposition. CONSTITUTION:The outer frames 8 and 9 are formed by molding the plastic or rubber which can ultrasonically deposited and the battery cans 10 and 11 are formed by molding conductive materials. Then, the battery can 10 is pressed in the outer frame 8, the positive flux 1 is inserted in the battery can 10, and the separator 4 is put on it. Subsequently, the battery can 11 is pressed in the outer frame 9 and the negative flux 2 or the negative member 12 such as lithium, zinc, etc. is inserted in the battery can 11. After the electrolyte 3 is injected to it, a thin battery is formed by overlapping them, immediately ultrasonically depositing the outer frames 8 and 9, and sealing them. In this case, it is desirable to use the protective member 13 for preventing the separator 4 from being damaged. |
