摘要：
A method for manufacturing non lead added anode zinc material for manganese dry batteries comprising compounding a zinc alloy by melting zinc, 0.1 mass % or more and 0.7 mass % or less of bismuth and other impurity elements inevitably contained in zinc in a melting furnace; casting the compounded molten zinc alloy to a molded material in the form of a band or in the form of a bar; rolling the molded material in band form to form a zinc alloy sheet; and punching the rolled zinc alloy sheet in a designated thickness into a designated shape.
