Zusammenfassung:	A non-aqueous electrolyte secondary battery includes an electrode group, and a non-aqueous electrolyte. The electrode group includes a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. The negative electrode includes a negative electrode current collector having a belt-like shape and having a first end and a second end in a short-side direction of the negative electrode current collector. The negative electrode current collector includes at least one slit group constituted of a plurality of slits extending in a form of a dashed line along the short-side direction from one end of the first end and the second end toward the other end, and a hole formed on the other end side of the plurality of slits and having a width larger than an average width of the plurality of slits.
