    • A sheet-shaped electrode comprising a polymeric active material (1) and a collector (2) having a plurality of penetrating pores (3), a method of producing the same, and a secondary battery containing the sheet-shaped electrode as a positive electrode. The plurality of the pores provided on the sheet-shaped collector enlarges the contact area between the collector and the polymeric active material, so that close contact between these two members is improved. A polyaniline layer which is prepared by electrochemical polymerization of an aniline type compound in the presence of sulfuric acid or sulfonic acids is applied on both faces of the collector (aluminum) as the polymeric active material. In a secondary battery which comprises the sheet-shaped electrode as a positive electrode, the positive and a negative electrodes are alternately folded with a separator interposed therebetween. Terminals for both electrodes of the collector are arranged at the opposite end portions of the positive electrode and the negative electrode, respectively.
