Zusammenfassung:	The purpose of the present disclosure is to provide a non-aqueous electrolyte secondary battery that can suppress damage to an electrode body in the vicinity of an end of an insulation tape due to repetition of charging and discharging. A non-aqueous electrolyte secondary battery (10) is characterized by comprising: an exterior body (15); a wound-type electrode body (14) which is housed in the exterior body (15) and in which a positive electrode (11) and a negative electrode (12) are wound with a separator (13) interposed therebetween; and an insulation tape stuck to the electrode body (14). The non-aqueous electrolyte secondary battery is also characterized in that the insulation tape has a base material layer and an adhesive layer that is provided on a main surface of the base material layer, and a side surface of the base material layer is non-vertically inclined with respect to the main surface.
