Abstract: In this non-aqueous electrolyte secondary battery, a positive terminal and a negative terminal extend in a first direction, protrude from a laminated cell stack, and are provided so that a center line is interposed therebetwen, the center line passing through a midpoint of both ends of the laminated cell stack in a second direction orthogonal to the first direction and extending in the first direction when the laminated cell stack is seen in plan view, and a first terminal with higher heat dissipation efficiency among the positive terminal and the negative terminal is provided in a location closer to the center line than a location of a second terminal with lower heat dissipation efficiency among the positive terminal and the negative terminal.
