NOVELTY - An all-solid type polymer battery (21) has a solid electrolyte layer (2) arranged between a positive electrode layer (1) and a negative electrode layer (3), and containing a secondary dry polymer electrolyte. The positive electrode layer has a positive electrode active material layer (6) containing active material and primary dry polymer electrolyte. The primary and secondary polymer electrolytes contain a matrix polymer having a supporting electrolyte containing lithium, and a polymer chain containing an electron-donating element.    USE - All-solid type polymer battery is used as power supply for handheld terminal, portable electronic device and medical device.    ADVANTAGE - The all-solid type polymer battery has excellent reliability, safety, capacity and output characteristics. The reduction of battery capacity after cold storage is prevented.    DETAILED DESCRIPTION - An all-solid type polymer battery has a solid electrolyte layer arranged between a positive electrode layer and a negative electrode layer, and containing a secondary dry polymer electrolyte. The positive electrode layer has a positive electrode active material layer containing active material and primary dry polymer electrolyte, formed at surface of a positive electrode current collection layer (5). The negative electrode layer has a negative electrode active material layer (8) containing active material, formed at surface of a negative electrode current collection layer (7). The primary and secondary polymer electrolytes contain a matrix polymer having a supporting electrolyte containing lithium, and a polymer chain containing an electron-donating element. The molar ratio of lithium with respect to electron-donating element in electrolyte layer is more than molar ratio of lithium with respect to electron-donating element in positive electrode active material layer.
