1. A solid-state battery, comprising a solid-state battery cell, and a battery case for accommodating the solid-state battery cell, wherein
the solid-state battery cell is a stack comprising a positive electrode, a negative electrode, and a solid electrolyte present between the positive electrode and the negative electrode,
the battery case comprises a pressing portion that applies surface pressure to the solid-state battery cell, on a face extending substantially perpendicular to a stacking direction of the stack,
a heat sink is disposed in the pressing portion,
the solid-state battery comprises an expansion material between the solid-state battery cell and the battery case, and
the expansion material expands in volume by water absorption or a chemical reaction.
