Abstract: A battery includes: a power generation element that includes a plurality of unit cells each including a positive electrode layer, a negative electrode layer, and a solid electrolyte layer. The power generation element includes a first side surface and a second side surface, and in the first side surface, first depressions and first projections are arranged alternately, in the second side surface, second depressions and second projections are arranged alternately, each of the first depressions includes a first inclination surface, and each of the second depressions includes a second inclination surface. The battery further includes: a first insulating member arranged in the first depressions; a second insulating member arranged in the second depressions; a first conductive member; and a second conductive member. The positive electrode layers are electrically connected via the first conductive member, and the negative electrode layers are electrically connected via the second conductive member.
