PROBLEM TO BE SOLVED: To provide an all-solid battery that increases heat radiation efficiency at a plane-directional center part of the all-solid battery so as to improve cycle durability.SOLUTION: An all-solid battery according to the present invention has a positive-electrode collector layer, a positive-electrode active material layer, a solid electrolyte layer, a negative active material layer, and a negative-electrode collector layer stacked. A collector layer 100 of the all-solid battery according to the present invention comprises: a collection part 110 provided at its end part; and a heat radiation path 120 formed continuously from its plane-directional center part to the collection part 110, the heat radiation path 120 having larger heat conductivity than a region of the collector layer 100 other than the heat radiation path.SELECTED DRAWING: Figure 1 |
