PURPOSE:To improve the leak-proof performance by employing an adhesives as an insulation member when performing insulative sealing between cathode terminal and a case above anode. CONSTITUTION:A cathode agent 6, electrolyte impregnated member 9, separator 8 and anode agent 7 are sequentially inserted through a circular insulated gasket 10 into a case 3 above anode where an anode terminal 1 is sealed with an insulation member 11, then it is covered with a below anode case and the circumferential section of both cases are welded to form a cell. A pan shaped current collector 5 is welded to said cathode terminal 1 then an adhesives 11 is filled without gap between said cathode current collector 5 and cathode terminal 1 and above anode case 3. An epoxy, acryl, amide or rubber group adhesives are employed as said adhesives, while a pillar having cross cross-section or partial projection is preferable as the cathode terminal 1. |
