Disclosed is a modified metal oxide sol that has a large hydrophilizing effect and antistatic effect, can be produced at low cost and is capable of being a coating. Specifically disclosed is a modified metal oxide sol characterized by modification by a functional group represented by formula (1) at 0.55-5.5 mmol per 1 g of metal oxide sol. MOS(═O) 2 —R 1 —Si(CH 3 ) n (—O—) 3-n (1) {In the formula, M is a hydrogen ion, C 1-4 alkyl group, metal ion or ammonium (NR 2 4 ) group; R l is a C 1-10 alkylene group (may have urethane bonds or urea bonds in the main alkylene chain); R 2 may be the same or different and is a C 1-5 alkyl group or a hydrogen atom; and n represents 0 or 1}. |
