  "textContent": "Provided are an assembled battery and a battery pack that are easy to design and assemble and that make it possible to suppress destruction of a battery case and any decrease in performance of a battery due to deformation of a battery cell while suppressing transmission of heat between battery cells when there is an abnormality. Each battery cell (2) has an electrode surface (2a) that has an electrode (3), and an outer peripheral surface (2b) that is a surface orthogonal to the electrode surface (2a). The battery cells (2) are connected in series or in parallel with the electrode (3) and a connector, etc. (not shown), interposed therebetween. The outer peripheral surfaces of the battery cells (2) are covered by a flameproof material (4), and the outer peripheral surface of the flameproof material (4) is furthermore covered by an elastic member (5), whereby an assembled battery (6) is configured. The elastic member (5) is a cylindrical body of which both ends are open, and the elastic member (5) covers the outer peripheral surfaces of the battery cells (2) and the flameproof material (4) in the circumferential direction.",
