    Abstract: A cable type secondary battery includes an inner electrode support; and a sheet-like inner electrode—separation layer—outer electrode complex which is spirally wound around the outer side of the inner electrode support. The inner electrode—separation layer—outer electrode complex is formed such that an inner electrode, a separation layer, and an outer electrode are compressed integrally. According to one embodiment, an electrode and a separation layer are bonded integrally so that the separation layer in close contact with the electrode absorbs electrolyte so as to induce a uniform supply of the electrolyte to an outer electrode active material layer, thereby increasing the stability and performance of a cable type secondary battery. In addition, the cable type secondary battery has a sheet-like electrode, whereby the resistance of the cable type secondary battery is reduced and the performance of the battery may be improved.
