PURPOSE: A flat type cell, wherein a voltage drop in a contact surface between a positive electrode active material and a positive electrode can is prevented by forming a conductive film to a bottom surface of the positive electrode can and laminating the positive electrode active material under pressure to said film.
CONSTITUTION: A conductive film 10, mixing a high molecular compound of polyisobutylene, polybutene, etc., carbonaceous graphite or the like and Ti, Ni, Al, Sn, Zn, Pb, Fe, Mg, Cu, Cd, etc., is formed to the bottom surface of a positive electrode can 1. After a positive electrode active material 4 is laminated under pressure to this film 10, a flat type cell of button type or the like is assembled. By this cell constitution, an electrical contact condition between the can 1 and the material 4 is improved, and internal resistance of the cell can be prevented from increasing. Further capacity of housing the material 4 can be increased.
