Nonaqueous electrolyte battery having exposed electrode collector portions

A nonaqueous electrolyte battery capable of minimizing damage if the battery is crushed by pressure is disclosed. The nonaqueous electrolyte battery according to the present invention includes a spiral coil formed by, through a separator, winding a positive electrode having an elongated positive-electrode collector with two sides on each of which an active material for the positive electrode has been formed and a negative electrode having an elongated negative-electrode collector with two sides on each of which an active material for the negative electrode has been formed. Wherein the positive electrode has a lengthwise directional end which has two sides, each of which is provided with a positive-electrode-collector exposed portion in which a positive-electrode collector is exposed, the negative electrode has a lengthwise directional end which has two sides, each of which is provided with a negative-electrode-collector exposed portion in which a negative-electrode collector is exposed, and the positive-electrode-collector exposed portion and the negative-electrode-collector exposed portion cover the coil one or more times through the separator.
