PROBLEM TO BE SOLVED: To provide a sealed battery having a structure in which an opening such as an electrolyte inlet in a battery can be securely sealed with ease and safety. SOLUTION: A structure which can be inserted into an opening is used as a sealing member 8 for sealing the opening. A portion, which can be heated directly from the outside, between a member 6 forming the opening and the sealing member 8 is welded or soldered so as to seal the opening. Furthermore, at least a part between both the members other than the portion to be welded or soldered is filled with a filler 11 solidified through a fused state. Consequently, it is possible to securely seal the opening with safety. Moreover, since the inside of a battery jar is not heated in sealing, there is no problem of occurrence of fire. |
