PROBLEM TO BE SOLVED: To prevent the occurrence of interference fringes and to improve weatherability, etc., by providing the surface of a base material with a cured film coated with a coating compsn. contg. an org. silicon compd. and/or the hydrolyzate thereof and specific composite particulates. SOLUTION: This optical member has the cured film formed by coating the front surface of the base material with the coating compsn. contg. the org. silicon compd. and/or the hydrolyzate thereof (component A) and the composite particulates (component B) mainly consisting of titanium oxide, zirconium oxide and silicon oxide and having an average grain size of 1 to 200μm and curing the coating. The org. silicon compd. expressed by formula (R<1> )a (R<3> )b Si(OR<2> )4-(a+b) used as the component A includes γ-glycidoxypropyl trimethoxysilane, etc. In the formula, R<1> , R<3> respectively denote the org. groups selected from a group consisting of alkyl groups, etc., R<2> denotes the org. group selected from a group consisting of an alkyl group, alkoxyalky group, acyl group and phenyl group; (a) and (b) denote 0 or an integer of 1. |
