PROBLEM TO BE SOLVED: To provide a battery that is reusable after a safety mechanism has operated and that ensures energy density by reducing volume occupying a generating element inside the battery to a minimum, as well as that prevents the battery and an external load circuit from being heated excessively due to an excessively heavily current charging/discharging, short circuiting, etc. SOLUTION: This battery is constituted by paying attention to a characteristic of a solid electrolyte that an electrolyte is secured inside a battery and does not evaporate, the battery having high energy density and superior safety and practicality by connecting a PTC element 4 (or using both the PTC element 4 and a fuse) between at least one end part of a positive terminal 11 or a negative terminal 18 and an electrode to be connected to the terminal, without providing a special separating means from the electrolyte and the PTC element 4 or the fuse in a battery jar of an entire solid battery using the solid electrolyte. |
