NOVELTY - A non-aqueous electrolyte battery (50) comprises two strip shaped electrodes; electrode leads disposed to extend in such a manner that one end portion side that overlaps with electrode is connected to electrode in the vicinity of its short side and other end side protrudes from one side edge of electrode; separator; and electrolyte, where laminated body that is formed by laminating electrodes through separator is wound in longitudinal direction with one end to which first lead is connected made as initial end and a wound electrode body (53) is formed that is held in battery exterior body.    USE - As non-aqueous electrolyte battery (claimed) such as lithium ion battery used as portable power source in portable electronic apparatus such as camera-integrated Video Tape Recorder (VTR), cellular phone, and a notebook PC.    ADVANTAGE - The battery provides highly stable non-aqueous electrolyte battery by suppressing stress, which is a cause of damage. The non-aqueous electrolyte battery prevents the separator from being damaged. The damage of the separation is suppressed, and a short circuit between the positive electrode and the negative electrode is suppressed, such that it is possible to realize a high level of safety. The battery makes it possible to obtain a relatively high effect.    DETAILED DESCRIPTION - A non-aqueous electrolyte battery (50) comprises: a first electrode having a strip shape; a second electrode having a strip shape; a first electrode lead that is disposed to extend in such a manner that one end portion side that overlaps with the first electrode is connected to the first electrode in the vicinity of its short side and the other end side protrudes from one side edge of the first electrode; a second electrode lead that is disposed to extend in such a manner that one end side that overlaps with the second electrode is connected to the second electrode in the vicinity of its short side and the other end side protrudes from one side edge of the second electrode; a separator having a strip shape, which is disposed between the first electrode and the second electrode, and has external dimensions larger than those of both the first electrode and the second electrode; and non-aqueous electrolyte, where a laminated electrode body, which is obtained by laminating the first electrode and the second electrode through the separator in such a manner that the second electrode lead is disposed at the other end portion of the second electrode not opposite to one end portion of the first electrode to which the first electrode lead is connected, is wound in a longitudinal direction with one end to which the first electrode lead is connected made as an initial end, and a wound electrode body (53) is obtained, in regard to the laminated electrode body, the second electrode and the second electrode lead are connected to each other in such a manner that an electrode connection side one end, which is connected to the second electrode, of the second electrode lead is located at a position that is opposite to either the first electrode or the second electrode, or a position that is opposite to neither the first electrode nor the second electrode, and the wound electrode body is accommodated in a battery exterior body that covers and seals the wound electrode body together with the non-aqueous electrolyte; or comprises several sheets of first electrodes having a rectangular shape; several sheets of second electrodes having a rectangular shape; the first electrode leads; the second electrode leads; sheets of separators having rectangular shape; and the non-aqueous electrolyte.
