Abstract: A lithium-ion rechargeable battery (1) provided with: a battery unit (100) including a metal substrate (10) and a battery part (20) configured by laminating thin films on the substrate (10); and a shell (200) provided on the surface of the substrate (10), on which the battery part (20) is formed, to seal the substrate (10) and the battery unit (100). The shell (200) includes a laminated film (30) formed by laminating a metal layer (33) and various types of resin layers. Consequently, the thickness of the thin-film type lithium-ion rechargeable battery including a solid electrolyte is reduced.
