Claim 8:
9. The solid-state battery according to claim 4, wherein a plurality of power generation elements connected in series are stacked on top of each other and contained between the can bottom and the flat portion,
an inner surface of the base-end portion has a second border between a side surface contiguous to the inner surface of the curved-surface portion and a curvature surface contiguous to the side surface and an inner surface of the stepped portion,
if that power generation element located closest to the flat portion is a cathode material layer, a height distance between the inner surface of the flat portion and the second border is smaller than a height distance between the inner surface of the flat portion and an upper edge of an outer peripheral surface of that anode material layer which is closest to the flat portion, and,
if that power generation element located closest to the flat portion is an anode material layer, the height distance between the inner surface of the flat portion and the second border is smaller than a height distance between the inner surface of the flat portion and an upper edge of an outer peripheral surface of that cathode material layer which is closest to the flat portion.
