NOVELTY - A nonaqueous electrolyte secondary battery comprises positive electrode plate in which positive electrode mixture layer is formed on positive electrode core, negative electrode plate in which negative electrode mixture layer is formed on negative electrode core, winding electrode component (14), nonaqueous electrolyte, pressure sensitive-type electric current breaker mechanism (27) electrically connected to at least one of the positive electrode plate and the negative electrode plate, and exterior component (25).    USE - Nonaqueous electrolyte secondary battery is used for electric vehicle and hybrid electric vehicle.    ADVANTAGE - The safe nonaqueous electrolyte secondary battery has high battery capacity and high charging/discharging characteristic.    DETAILED DESCRIPTION - A nonaqueous electrolyte secondary battery comprises positive electrode plate in which a positive electrode mixture layer is formed on a positive electrode core, negative electrode plate in which a negative electrode mixture layer is formed on a negative electrode core, winding electrode component in which the positive electrode plate and the negative electrode plate are insulated on both sides of a separator, nonaqueous electrolyte, pressure sensitive-type electric current breaker mechanism electrically connected to at least one of the positive electrode plate and the negative electrode plate, and exterior component. The exterior component comprises electrolytic solution which is existed outside of the electrode component. When the exterior component is horizontally positioned, the height of the liquid level of the electrolytic solution does not contact a structural component of the electric current interruption mechanism.
