Title: LITHIUM ION SECONDARY BATTERY
Abstract:
This lithium ion secondary battery 1 is provided with: a battery unit 100 including a metallic substrate 10 and a battery section 20 formed by stacking thin films on the substrate 10; and a cladding section 200 provided on the surface side for forming the battery section 20 on the substrate 10, and sealing the substrate 10 and the battery unit 100. The cladding section 200 has a stacked film 30 that is formed by stacking a metal layer 33 and various types of resin layers. Consequently, thinning is achieved of this thin film-type lithium ion secondary battery provided with a solid electrolyte.
