비수 전해질 전지(11)는 바이폴라 전극 유닛, 및 비수 전해질을 포함하는 절연층(6)을 구비한다. 절연층은 상기 유닛의 바이폴라 전극(11)의 집전체(3)의 양면 상에서 정극 및 부극 활물질 층(4,5)을 피복한다. 상기 유닛은 서로 대향하도록 배치된 평탄부(8) 및 상기 평탄부 사이에 배치되어 상기 평탄부를 접속시키는 굴곡부(12)를 갖도록 미리 결정된 길이마다 절첩된다. 각각의 굴곡부의 외측 면 상에 위치하는 전극의 절연층의 한 부분의 두께(t)는, 각각의 평탄부 상에 위치하는 절연층의 다른 부분의 두께(t0)보다 더 크도록 설정된다.

    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.
