PURPOSE:To enhance the liquid leakage resistance of a thin sealed storage battary by sealing the contact areas of each terminal lug and a case by means of an adhesive having rubber elasticity, and caulking said contact areas by means of a cylindrical metallic ring. CONSTITUTION:A positive terminal lug 5 and a negative terminal lug 6, respectively, are led outside from a positive and a negative plate 1 and 2 through the opening 7 of a case 4. The led out part 8 of each of the terminal lugs 5 and 6 is surrounded by the convex section of the case 4, the contact areas of the led out part 8 and the case 4 are sealed with an adhesive 9 and the convex sections are caulked with cylindrical metallic rings 10. In addition, the areas of the opening 7 other than the led out parts 8 are airtightly sealed through fusion by use of a heater, ultrasonic wave, laser or the like. As the adhesive 9 used to seal the spaces formed between the terminal lugs 5 and 6 and the case, 4 an electrolyte resistant material having rubber elasticity, for example, a synthetic rubber such as butyl rubber, nitrile rubber or butadiene-styrene rubber, an epoxy system adhesive or the like is employed. |
