Abstract

The non-aqueous electrolyte secondary battery has an electrode body (14) and an outer can. The electrode body (14) has a positive electrode (11) and a negative electrode (12) wound around it with a separator (13). The outer can is a bottomed cylindrical shape and houses the electrode body (14). The positive electrode (11) has a starting end (50) on the outside of the winding of the negative electrode (12). The negative electrode (12) has a negative electrode lead (21). One end of the negative electrode lead (21) is connected to the starting end (70) side of the negative electrode (12), and the other end is connected to the outer can. Adhesive tape (60) is attached to the back of the negative electrode (12) at position A opposite to the starting end (50) of the positive electrode (11).
