NOVELTY - The module has multiple solid batteries (10) equipped with an electric power generation part (4) and an overcharge prevention part (7) between a positive electrode collector (5) and a negative electrode collector (6) that are laminated such that the collectors are in contact with each other. Electric conductivity increases above predetermined voltage in a polymeric material of the prevention part. The prevention part is provided in outer periphery of the generation part. A positive electrode layer (1) and a negative electrode layer (2) are formed on the positive or negative collector.    USE - Solid battery module e.g. secondary battery module such as lithium solid battery module, for use in a small power supply of a portable apparatus and a large-sized power supply of an electric vehicle and a hybrid vehicle such as eco-friendly car.    ADVANTAGE - The solid batteries are equipped with the electric power generation part and the overcharge prevention part between the positive electrode collector and the negative electrode collector that are laminated such that the collectors are in contact with each other, so that a cell is short-circuited for more than the predetermined voltage. The prevention part is provided in the outer periphery of the generation part, without affecting electrochemical reaction in the generation part by the prevention part, so that overcharge control for each cell is performed in an easy manner, thus preventing each single battery to be set in the overcharge state in an appropriate manner by the module, and improving safety and capacity of the secondary battery.    DETAILED DESCRIPTION - The polymeric material is chosen from polythiophene, polyaniline, polyparaphenylene or polyparaphenylene vinylene.
