PROBLEM TO BE SOLVED: To provide a flat organic electrolyte battery keeping liquid leakage proofing property at high temperature preservation by restraining flexural elastic modulus of a resin material of a gasket used for the battery, and restraining increase of internal resistance caused by gas in the battery. SOLUTION: The flat organic electrolyte battery, enclosing a power generating element containing organic electrolyte in its insides, is formed by calking a bottomed cylinder-shaped case serving as one electrode and a bottomed cylinder-shaped sealing plate serving as the other electrode with a ring-shaped gasket insulating the case from the sealing plate interposed in between. By using a resin material having a flexural elastic modulus of 7,500 to 10,000 kg/cm<SP>2</SP>or less for the gasket, the liquid leakage proofing property at high temperature preservation can be maintained, and the increase of internal resistance can be restrained.
