PROBLEM TO BE SOLVED: To provide a producing method of an article having a fine rugged surface coated with a film which has high heat resistance, which produces no cracks and which does not peel from the base body. SOLUTION: A solgel material is disposed in a film state as adhered between a base body and a molding die, and then heated to form a gelated film having the reversal shape of the surface of the molding die on the base body surface. In this producing method of an article having a rugged surface, the solgel material contains (A) a silane compd. expressed by formula I of2 SiX2 (R is an alkyl group, X is an alkoxyl group or halogen atom) and (B) a compd. expressed by R'SIX'3 (R' is an aryl group or aryl substituent, X' is an alkoxyl group or halogen atom). |
