A dispersion liquid was prepared by adding 100 g (31 g in terms of ZrO2) of zirconium hydroxide to 100 g of water, followed by well stirring. Next, as a first addition of oxalic acid, 31.7 g (a mol ratio of oxalic acid to Zr=1.0) of oxalic acid dihydrate was added to the dispersion liquid, followed by heating at 90° C. for 15 minutes. Next, as a second addition of oxalic acid, 15.8 g (a mol ratio of oxalic acid to Zr=0.5) of oxalic acid dihydrate was added to the dispersion liquid, followed by heating at 90° C. for 15 minutes to obtain a sol. When diluted to 0.5% by weight in terms of ZrO2, the zeta potential of the sol was −61 mV and the particle diameter D50 was 65 nm.
