PROBLEM TO BE SOLVED: To provide a battery of which charging and discharging efficiency and charging and discharging capacity are improved. SOLUTION: A positive pole 1 of a battery is composed of a sheet-like active material 7 carried on a lattice-like collector part 8 and carbonaceous material layer 10 to electrically connect the sheet-like active material 7 and the electric collector 8. The carbonaceous material layer 10 is formed by applying phenolic resin, for example, to the surface of the sheet-like active material 7 and the surface of the collector part 8 and carbonizing the resin while applying pressure to the whole of the resin. |
