    摘要： Provided is a zinc negative electrode excellent in repeat resistance and excellent in charge and discharge cycle characteristics even in a high charge and discharge rate, a method for fabricating the same, a secondary battery using the zinc negative electrode, and a method for fabricating the same. The zinc negative electrode is used for a secondary battery and includes an active material portion, a current collector, and a non-electronically conductive reaction space divider. The active material portion forms zinc during charging and forms a zinc oxide during discharging. The zinc is used as a negative-electrode active material. The current collector is electrically connected to the active material portion. The non-electronically conductive reaction space divider is integrally formed with or connected to the current collector and/or the active material portion. The reaction space divider has a plurality of electrolyte holder portions consisting of a space configured to hold a liquid electrolyte.
