PROBLEM TO BE SOLVED: To provide an all-solid battery arranged so that the rise in battery temperature can be prevented by efficiently isolating between a positive electrode and a negative electrode active material layer when the all-solid battery is raised in temperature.SOLUTION: An all-solid battery 100 of the present invention comprises a laminate including a positive electrode current collector layer, a positive electrode active material layer, a separator layer, a negative electrode active material layer, and a negative electrode current collector layer. In the all-solid battery, the separator layer has solid electrolyte particles, and a polymer binder binding between the solid electrolyte particles. The all-solid battery 100 has a peripheral edge member 210 disposed on its peripheral edge. The polymer binder is larger, in thermal expansion coefficient, than the peripheral edge member 210.SELECTED DRAWING: Figure 2 |
