PROBLEM TO BE SOLVED: To provide an all solid secondary battery constructed small and light, equipped with excellent high capacity, large current discharging characteristic, unlikely to cause liquid leakage or fire breaking, having small interface impedance between a positive electrode, negative electrode and an electrolyte layer, and having good cyclic characteristics. SOLUTION: An all solid secondary battery is configured so that an electrolyte layer consisting of gel-form organic polymer electrolytic substance is inserted between a positive and a negative electrode and fixed, wherein the positive electrode is made of a positive electrode active material and gel-form organic polymer electrolyte while the negative electrode is formed from a negative electrode active material and gel-form organic polymer electrolyte. The gel-form organic polymer electrolyte should preferably consist of a compound including an organic polymer having a relative permittivity 4 or above, non- protonic solvent and electrolyte salt, or the organic polymer should preferably be acrylonitrile polymer. |
