NOVELTY - The organic electrolyte primary battery has electrode assembly comprising winding in shape of coil so that order of separator, cathode, separator and anode is repeated. A cathode lead (5) is connected to outer periphery edge portion of cathode. A reaction suppression layer (11) is provided between outer periphery edge-portion of anode and cathode. A electrolyte-liquid holding layer (12) is provided at reaction suppression layer.    USE - As power supply.    ADVANTAGE - The organic-electrolyte primary battery has excellent over-discharge safety, high capacitance, and prevents internal short-circuit at the time of over-discharge.    DETAILED DESCRIPTION - The organic electrolyte primary battery has a battery case holding a cathode (2) consisting of alkali metal or its alloy as main component, an anode (1) filled with a mixture layer consisting of active material on an electroconductive porous core material, a separator (3) and an organic electrolyte. The separator is inserted between the anode and the cathode. The structure of electrode assembly comprises a winding in the shape of coil so that order of separator, cathode, separator and anode is repeated towards inside from the outer periphery side. A cathode lead (5) is connected to the outer periphery edge portion of the cathode, and the region does not oppose anode with separator. The outer periphery edge portion of anode is covered by electric insulation material. A reaction suppression layer (11) is provided between the outer periphery edge-portion of anode and cathode. A electrolyte-liquid holding layer (12) is provided at reaction suppression layer and opposing region of anode-cathode and separator. The electrolyte-liquid holding layer (120 contains non-woven fabric chosen from polypropylene and/or polyethylene.
