Abstract: A solid-state battery is provided that allows the exterior can to be sufficiently crimped onto the seal can without leading to improper crimping, thus preventing entry of water from the outside. The solid-state battery 1 includes an exterior can 2, a seal can 3, facing the exterior can 2 and a power generation element 4 contained in the space between the exterior can 2 and seal can 3. The seal can 3 includes a flat portion 31 and a peripheral wall 32 that are contiguous to each other with a curved-surface portion 33 provided therebetween. A first clearance g1 is defined between the upper edge of the outer peripheral surface of the power generation element 4 and the border 10 between the inner surface of the flat portion 31 and the inner surface of the curved-surface portion 33, the first clearance having a radial dimension not larger than 2.0 mm at a position where its dimension is at its largest.
