70 ml of purified water was added to 8 g of anhydrous copper acetate (manufactured by Wako Pure Chemical Industries, Ltd.). Thereto was added 0.66 ml of 64 wt % hydrazine hydrate at room temperature of 25° C. while stirring so as to give a molar ratio of hydrazine to copper acetate of 0.3, thereby to carry out the reaction to obtain a precipitate of cuprous oxide. The average primary particle diameter of the resulting cuprous oxide was large, namely, 200 nm.
