摘要： 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.
