摘要： The present invention provides a zinc foil that can be used as a negative electrode active material, and in a battery including the zinc foil as a negative electrode active material, the amount of gas generated during long term storage of the battery is reduced as compared with that in a battery including a conventional zinc foil. The zinc foil contains zinc as a main material and bismuth. The bismuth content is 100 ppm or more and 10000 ppm or less on a mass basis. The zinc crystal grain size is 0.2 µm or more and 8 µm or less. The bismuth crystal grain size is less than 1000 nm, as measured in a backscattered electron image obtained using a scanning electron microscope. The zinc foil is free of aluminum and/or lead, or even if the zinc foil contains aluminum and/or lead, the aluminum content is 1% or less on a mass basis and/or the lead content is 200 ppm or less on a mass basis.
