Abstract: A battery includes a power generating element group including multiple laminated power generating elements each of which contains a solid electrolyte, and a first member in contact with a principal surface of a first power generating element that is one among the multiple power generating elements. The principal surface includes a central portion and an end portion with a ring-like shape surrounding the central portion in a plan view. The first member includes a central region overlapping with the central portion of the principal surface in a plan view, and an end region overlapping with the end portion of the principal surface in a plan view. At least one of the central region or the end region is in contact with the principal surface. A Young's modulus of the end region is smaller than that of the central region.
