First claim

Opening claim text (preview).

What is claimed is: 1 . A battery comprising: an electrode body in which cathode bodies and anode bodies are alternately laminated via separators; and a laminate exterior body that houses the electrode body, wherein the laminate exterior body includes a hard layer at a portion overlapping the electrode body when viewed in a thickness direction of the electrode body. 2 . The battery according to claim 1 , wherein the hard layer has an electrical insulation property. 3 . The battery according to claim 2 , wherein the hard layer includes at least either of ceramics and glass. 4 . The battery according to claim 3 , wherein: the laminate exterior body is flat; and each of two principal surfaces of the laminate exterior body includes a surface on the electrode body side. 5 . A module comprising: a plurality of the batteries according to claim 1 ; and a metal case that houses the batteries.
