Zusammenfassung:	PROBLEM TO BE SOLVED: To produce an indium hydroxide powder, and an indium oxide powder having an even particle size, and a narrow particle size distribution width.SOLUTION: In a method for producing an indium oxide powder by calcining an indium hydroxide powder obtained by electrolytic reaction using indium as an anode, the indium hydroxide powder is produced by electrolyzing in a solubility range of indium hydroxide powder of 10to 10mol/L using an ammonium nitrate aqueous solution as an electrolytic solution.
