1. A battery comprising:
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 first principal surface of a first power generating element that is one among the multiple power generating elements, wherein:
the first principal surface includes:
a central portion; and
an end portion with a ring-like shape surrounding the central portion in a plan view of the first principal surface,
the first member includes:
a first central region overlapping with the central portion of the first principal surface in a plan view of the first member; and
a first end region with a ring-like shape surrounding the first central region and overlapping with the end portion of the first principal surface in the plan view of the first member,
a thickness of the first central region is equal to a thickness of the first end region,
at least one of the first central region or the first end region is in contact with the first principal surface, and
a Young's modulus of the first end region is smaller than a Young's modulus of the first central region.
