Title: SECONDARY BATTERY AND DEVICE
Abstract:
The present invention provides a secondary battery that prevents mutual positional displacement due to vibration or the like with respect to a substrate, in particular, a substrate disposed on a low step portion formed by a step portion. The present invention pertains to a secondary battery 100A obtained by sealing, in an exterior body 6, an electrolyte and an electrode assembly including a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode, wherein the secondary battery has: one or more step portions 15 each formed by two upper surfaces 11, 21 having mutually different heights; and a sealing portion on at least one side surface of a low step portion 10 having a height of the upper surface that is relatively low. The sealing portion is bendable in the thickness direction of the secondary battery. A bent sealing portion 50b formed when said sealing portion is bent serves as a stopper portion with respect to a substrate 60A disposed on the upper surface 11 of the low step portion 10.
