PURPOSE:To improve proof against the leakage by means of a resin layer made of a mixture of epoxy resin and a specific sort of other resin and interposed between a gasket in the sealed inlet and metal sealing plate. CONSTITUTION:A metal container 1 serving the mission of an anode terminal as well is filled with anode agent 2 made from silver oxide etc. and cathode agent 5 made from amalgamated zinc power is piled and filled on it via a separator 3 and an electrolyte retainer 4. The opening 1a of this container 1 is sealed with metal sealing plate 6 equipped with a gasket 7 and serving its additional mission as a cathode terminal, thus an alkaline battery can be formed. Then, a resin layer 8 shall be formed in the contact surface between the face of gasket 7 and metal sealing plate 6. This resin layer 8 is made from a material formed by mixing epoxy resin, such quantity of polyoxy-propylene amine as reacting on this resin and leaving a part of it as virgin, and such quantity of epoxy resin as more than the equivalent of said remaining virgin resin. |
