PURPOSE: A lead electrolyzing method is provided to easily obtain electrodeposited lead with a smooth electrodeposited surface without installation of a fluorine removal facility. CONSTITUTION: A lead electrolyzing method is characterized in that Noigen BN-1390 and Noigen BN-2560 are added into electrolyte at the rate of 1-700mg/L, the electric current density is less than 100A/m^2, and a lead-containing material is composed of lead 70-99 mass%, bismuth 0-30 mass%, and tin 0.04 mass% or less.
