Abstract: A battery includes an electrode layer, a counter-electrode layer placed opposite to the electrode layer, and a solid electrolyte layer located between the electrode layer and the counter-electrode layer. The electrode layer includes a collector, an electrode active material layer located between the collector and the solid electrolyte layer, and an insulating layer located between the collector and the solid electrolyte layer and bonded to the collector at ends of the electrode layer. The electrode active material layer has a region that does not overlap the insulating layer in plan view. The battery has an air gap, the air gap being located between the collector and the solid electrolyte layer and being contact with the insulating layer.

Abstract: A battery includes a power-generating element having at least one unit cell including an electrode layer, a counter-electrode layer, and an electrolyte layer located between the electrode layer and the counter-electrode layer and an insulating member covering the power-generating element. The insulating member includes a first member that includes a first principal surface covering portion covering a first principal surface of the power-generating element and a second member, joined to the first member, that includes a second principal surface covering portion covering a second principal surface of the power-generating element opposite to the first principal surface. A junction between the first member and the second member overlaps a side surface of the power-generating element when seen from a direction perpendicular to the side surface. An elastic modulus of the first member is higher than an elastic modulus of the second member.
