Battery and electric device

The embodiment of the invention aims to provide a battery and an electric device. The battery includes a laminate including a first conductive layer, a second conductive layer, and a first layer disposed between the first conductive layer and the second conductive layer and including an insulating material, a first conductive portion, a second layer, and a case; the first conductive part is electrically connected with the first conductive layer, and the first conductive part extends along a first direction away from the laminated body; the shell covers the laminated body, and the shell covers the first conductive part and a part of the structure of the second layer; when viewed in a third direction perpendicular to the first direction and the second direction, the second layer includes a first region overlapping the first conductive portion, and a second region separated from the first conductive portion, the second region having a first recess recessed toward the housing in the first direction. 本公开实施例的目的在于提供
