Aqueous basic aluminum chloride solution of concentration of 5.0% by weight on the basis of Al2O3 was produced by diluting commercialized aqueous basic aluminum chloride solution (23.5% by weight on the basis of Al2O3, 8.15% by weight of chloride ion, 83.3% of basicity, and pH 4.0) with pure water. The aqueous solution was passed through an acetate-type anion exchange resin column at space velocity 5 to obtain an aqueous basic aluminum acetate solution. The obtained aqueous solution was dried at 90° C. and atmospheric pressure to adjust the water content to be 20% to obtain a basic aluminum acetate solid. The obtained solid had 0.79 in a full width at half maximum of the peak measured by the x-ray diffractiometry described in the above-mentioned evaluation method.
