PURPOSE:To obtain thin and small cell having superior anti-liquid-leak performance and long life by forming the outer peripheral collar part of a cathode cab into flat form and performing glass etching and applying pressure onto said glass etched part by the bent part of the anode can through a resin packing. CONSTITUTION:Anode active substance 9 is stored in an anode can 5, and on the anode active substance, cathode active substance 10 which consists mainly of zinc and stored in a cathode can 4 is arranged through protective membrane 8, separator 7, and preservation membrane 6 interposed. Between both cans 4 and 5, nylon film adhesive 3 and a gasket 2, for example, are interposed, and caulk-sealing is performed, and a button-type cell is formed. The cathode can 4 is prepared from cover, inconel, iron-nickel alloy etc., and the outer peripheral collar part if formed in flat, and glass is etched onto the collar part, and glass frit 1 is formed. Pressure is applied onto this part by the bent part of the anode can 5 through the gasket 2. As the glass described above, the material, for example, having main constituent of borosilicic acid is used. |
