In a film packed battery, a battery power source comprising, at least, a cathode, an anode, an electrolyte, and a separator is packed with a film. In a method for producing film packed battery, a pre-charging step for charging the film packed battery while pressure is applied, for example, by sandwiching it between two flat plates is included at least once.
