  "textContent": "The purpose of the present disclosure is to provide a non-aqueous electrolyte secondary battery capable of suppressing deformation such as bending of a positive electrode and a negative electrode when an electrode body expands. The non-aqueous electrolyte secondary battery that is an example of the embodiment of the present disclosure has a wound electrode body in which a band-shaped positive electrode and a band-shaped negative electrode are wound with a separator interposed therebetween, and a cylindrical metal outer body accommodating the electrode body. The positive electrode or the negative electrode is exposed on the outermost peripheral surface of the electrode body, a fixing tape (50) having a base material layer (52) and an adhesive layer (54) is attached to the positive electrode or the negative electrode by the adhesive layer (54), and the base material layer (52) has a surface roughness (Sa) of 40 µm or more at least in a region having a width of 1 mm from the end portion.",
