PURPOSE:To make the promotion of improvement of liquid leak resistance, by using those mainly composed of specific two kinds of epoxy resin and hardening agent as a sealing agent for the sealed portion. CONSTITUTION:An anode compound 1, mainly composed of silver oxide powder, is contained in an anode can 4, and on top of this, with a separator 3, having a liquid holding layer, interposed, is provided a cathode compound 2 mainly composed of amalgamated zinc powder and contained in a cathode can 5. Between this anode can 4 and cathode can 5, is interposed a packing 6 to process a hermetically sealing, and the cell is constituted. At this time, on surfaces of the packing 6 of the sealed portion, is constructed a sealing agent layer 7. This sealing agent layer 7 is constructed by the main composition of epi-bis-type epoxy resin, fatty glyceryl ether type epoxy resin with structure of dimer acid, and the hardening agent. Its blending proportion is preferable for the dimer acid structural glyceryl ether type epoxy resin to be 20-80%. |
