Abstract
A non-aqueous electrolytic liquid secondary battery wherein a potential of a metal layer in an exterior body is kept high, and corrosion can be suppressed, wherein an average thickness tof a first part of an exterior body covering a first side surface where a negative and a positive electrode terminal of a power generation element exist is different from an average thickness tof a second part of the exterior body covering a second side surface that intersects the first. In plan view of the power generation element from a lamination direction, in a second direction orthogonal to a first direction in which the electrode terminals extend, the relationship of t<tis satisfied when a width of the negative electrode is larger than the positive, and in the second direction, the relationship of t>tis satisfied when the width of the negative electrode is smaller than the positive.
