1. A laminated battery, comprising:
a first collector layer;
a first electrode layer;
a solid electrolyte layer;
a second electrode layer; and
a second collector layer,
wherein the first electrode layer opposes the second electrode layer across the solid electrolyte layer,
an insulating layer is provided at an edge of the second electrode layer, in at least one edge of the laminated battery such that in a direction perpendicular to a stacking direction of the laminated battery, the edge of the second electrode layer is positioned closer to a center of the laminated battery than an edge of the first electrode layer, and an outer edge of the insulating layer is positioned closer to the center of the laminated battery than that of the edge of the first electrode layer,
a thickness of the insulating layer is smaller than a thickness of the second electrode layer,
a gap is provided between the insulating layer and the second collector layer, and
the insulating layer is provided on the solid electrolyte layer.
