Abstract

A non-aqueous electrolyte battery (11) is provided with a bipolar electrode unit and an insulating layer (6) including non-aqueous electrolyte. The insulating layer covers positive and negative electrode active material layers (4, 5) on both side surfaces of a current collector (3) of a bipolar electrode (11) of the unit. The unit is folded at every predetermined length to have flat portions (8) arranged to face each other and bent portions (12) arranged between the flat portions to connect the flat portions. A thickness (t) of one part of the insulating layer of the electrode, the one part being positioned on an outer side surface of each bent portion, is set to be larger than a thickness (t0) of the other part of the insulating layer, the other part being positioned on each flat portion.
