PROBLEM TO BE SOLVED: To provide a flat battery which can reduce defect caused by electrode plate breaking or active material layer removing from electrodes when the electrodes are inserted and set in a battery case, and enables good discharging characteristic by improving nonaqueous electrolyte soakage to the electrodes. SOLUTION: An adhesive tape 5 which has at least one opening or an adhesive tape which is made of base material having permeability for the nonaqueous electrolyte, is stuck on soles of the electrodes 7 which are disposed on an electrode inserting side of the battery case.
