PURPOSE:To prevent an inside short circuit in a battery by using a conductive core body, having a low melting point, susceptible to heat, and moreover liable to be adversely affected by moisture contained in a positive electrode mixture, for a positive electrode conductive core body. CONSTITUTION:A mixture sheet 1, made by sheetlikely forming a positive electrode mixture, is heat-treated and dried, and then is pressure-fixed to a conductive core body 2 such as a conductive film or aluminum. The mixture sheet is heat-treated, dried and then pressure-fixed to the conductive core body 2, consequently heat resistance is not required to the conductive core body 2, and also a core body, liable to be adversely affected by moisture contained in the positive electrode mixture, can be used. An inside short circuit, occurring due to the penetration of a burr of the conductive core body 2 through a separator, can be prevented by using a soft conductive film or aluminum, etc., for the conductive core body 2. |
