PROBLEM TO BE SOLVED: To provide an all-solid battery which is able to prevent, by a simple configuration, a temperature increase and short circuit of an all-solid battery by speedily cutting off ion conduction and heat transmission between electrodes when the all-solid battery exceeds an actuating temperature.SOLUTION: In an all-solid battery 100 according to the invention, a cathode collector layer 110, a cathode active material layer 120, a solid electrolyte layer 130, an anode active material layer 140, and an anode collector layer 150 are stacked in layers. In the all-solid battery 100, a pair of thermosensitive deformable metal members 160 are inserted at least partially in the solid electrolyte layer 130, between the solid electrolyte layer 130 and cathode active material layer 120, or between the solid electrolyte layer 130 and anode active material layer 140. When the all-solid battery 100 exceeds an actuating temperature, the pair of thermosensitive deformable metal members 160 deform so as to widen the distance between the cathode active material layer 120 and anode active material layer 140.SELECTED DRAWING: Figure 1 |
