PURPOSE:To suppress increase in internal resistance by forming a thin layer comprising a mixture of a gelling agent which hardly reduces a cathode active material and fine conductive powder on the surface, which is in contact with a cathode active material, of a separator between the cathode active material and an anode active material. CONSTITUTION:A thin layer 5 comprising a mixture of a gelling agent which hardly reduces a cathode active material, such as carbonyl polymer, and fine conductive powder is formed on the surface which is in contact with a cathode active material 2, of a separator 4 between the cathode active material 2 and an anode active material 8. The separator 4 is placed on the cathode active material 2 accommodated in a cathode can 1, and an electrolyte holding material 6 is placed thereon, then the negative active material 8 is combined with them to form an alkaline battery using silver oxide as the cathode. Thereby, generation of wrinkles in the separator 4 in a small battery in which electrolyte necessary for gelling of the gelling agent is difficult to contain is prevented. Therefore, increase in internal resistance is prevented and high rate discharge performance is increased. |
