PROBLEM TO BE SOLVED: To provide the method of cost effectively manufacturing basic nickel carbonates of high bulk density, which is proper to a use for nickel supplementation in a nickel bath in nickel-plating. SOLUTION: At least one nickelate solution among nickel sulfate, nickel nitrate and nickel chloride, at least one alkali carbonate solution selected from sodium carbonate, ammonium carbonate, potassium carbonate and lithium carbonate as a neutralizer, and carbon dioxide are quantitatively and simultaneously fed to a reactor. The generated basic nickel carbonate is successively taken out from the reactor to obtain the basic nickel carbonate of the tapping bulk density of 0.5 to 1.5 g/ml.
