PROBLEM TO BE SOLVED: To provide an alkaline battery having excellent liquid leakage resistance.SOLUTION: The alkaline battery is of a cylindrical shape configured by housing a cathode, a gel-like anode containing zinc alloy powder, a separator and an electrolyte consisting of an alkaline aqueous solution in a battery container consisting of an outer can, an anode terminal plate and a mouth sealing body, said alkaline battery being characterized in that the mouth sealing body is made of nylon and contains water by 1.5 mass% or less, that the anode terminal plate has one end of a metallic anode collector rod electrically connected thereto, the anode collector rod having the other end inserted into the gel-like anode through an open hole formed in the mouth sealing body, and that the surface of a portion of the anode collector rod in contact with the inner face of the mouth sealing body and a portion protruding from the mouth sealing body toward the gel-like anode side is covered with a rubber sealing agent for at least up to 1 mm from the edge of that portion in contact with the open hole of the mouth sealing body. |
