ABSTRACT:
The present invention is characterized in that an underlying layer solution containing a hydrolyzable compound represented byin-line-formulae description="In-line Formulae" end="lead"?X—(SiOX2)n—SiX3in-line-formulae description="In-line Formulae" end="tail"?(where X is at least one functional group selected from the group consisting of a halogen, an alkoxy group, and an isocyanate group and n is an integer equal to or more than 0) is brought into contact with a surface of a base material, the underlying layer solution is dried at a temperature less than 300° C. to form an underlying layer, a solution containing a silane-based compound is brought into contact with a surface of the underlying layer to cause chemical adsorption of the molecules of the silane-based compound to the surface of the underlying layer, and the base material is sintered at a temperature of 300° C. or more. This improves the water repellency, resistance, and heat resistance of a functional film composed of the silane-based compound, which is for modifying the properties of the surface of the base material.
