Abstract
The lithium-ion secondary battery has a portion where a thickness of a sealing member from a surface of an outer package to a surface of a lead in a laminating direction of electrode bodies on one side of the lead differs from that on the other side of the lead such that two leads connected to each electrode body are arranged within the same plane perpendicular to the laminating direction of the electrode bodies. The electrode bodies are laminated in the outer package such as to yield portions where only one of the planar leads of a first electrode body overlaps one of the planar leads of a second electrode body in the laminating direction of the electrode bodies in the opening part of the outer package.
