ALL-SOLID-STATE BATTERY

The all-solid-state battery includes: an exterior can with a bottom ; a seal can having a flat portion and facing the exterior can ; and a power generation element contained between the exterior can and seal can , where at least one of the inner surface of the bottom of the exterior can and the inner surface of the flat portion of the seal can includes a recess-protrusion structure. The battery includes a conductive sheet located between that one of the inner surfaces which includes the recess-protrusion structure and the power generation element , the conductive sheet having an ability to recover against a pressing force. The rate of recovery of the conductive sheet against a pressing force is not lower than 7%.
