BATTERY AND ELECTRIC APPARATUS

A battery including a multilayer body, a first conductive portion, a second layer, and a housing. The multilayer body includes a first conductive layer, a second conductive layer, and a first layer positioned therebetween, the first layer including an insulating material. The first conductive portion is electrically connected to the first conductive layer, and the first conductive portion extends in a first direction away from the multilayer body. The housing encompasses the multilayer body, and the housing encompasses a portion of the first conductive portion and a portion of the second layer. When viewed along a third direction perpendicular to both the first direction and the second direction, the second layer includes a first region that overlaps with the first conductive portion and a second region apart from the first conductive portion, where in the first direction, the second region has a first recess recessed toward the housing.
