In a stacked battery according to one aspect of the present disclosure, a first current collecting case includes: a first facing portion facing the electrode body in the stacking direction of the electrode body; and positive-electrode wall portions that extend from edge portions of the first facing portion so as to cover first side portions of the electrode body, and whose inner surfaces are electrically connected to edge sides of positive-electrode protruding portions. In the stacking direction of the electrode body, a second current collecting case includes: a second facing portion facing the electrode body in the stacking direction of the electrode body; and negative-electrode wall portions that extend from edge portions of the second facing portion so as to cover second side portions of the electrode body, and whose inner surfaces are electrically connected to edge sides of negative-electrode protruding portions.
