PURPOSE:To suppress an increase in internal resistance caused during charge and discharge of a solid secondary battery at a high temperature and extend the battery life. CONSTITUTION:After a polyamide resin is added to either or both of an electrode layer mainly containing an electrode material and a rubber binder and an electrolyte layer mainly containing an electrolyte and the rubber binder, both the layers are pressurized and integrated under heating. According to this manufacturing method, an increase in internal resistance in the charge and discharge at a high temperature is suppressed, and the charge/discharge cycle life of the battery can be extended. |
