Claim 0:
1. A non-aqueous electrolyte secondary battery comprising:
a laminated electrode body in which two or more cell units, in each of which a first electrode, a first separator, a second electrode, and a second separator are stacked in this order, are stacked; and
a non-aqueous electrolyte solution, wherein
the first electrode has a first current collector and a first active material layer,
the second electrode has a second current collector and a second active material layer,
an area of a principal surface of the first active material layer of the first electrode is larger than an area of a principal surface of the second active material layer of the second electrode,
each of an area of a principal surface of the first separator and an area of a principal surface of the second separator is larger than the area of the principal surface of the second active material layer of the second electrode,
the first active material layer includes a facing area which faces the second active material layer formed in a central portion of the first active material layer, and a non-facing area which does not face the second active material layer formed in an outer peripheral edge portion of the first active material layer,
the first separator and the first electrode are bonded to each other by a first adhesive,
the first adhesive which bonds the first electrode to the first separator is not disposed in the facing area of the first active material layer and is disposed in the non-facing area of the first active material layer,
the first separator and the second separator are not bonded to the second active material layer of the second electrode, and
the first separator and the second separator are joined to each other outside the second electrode.
