PROBLEM TO BE SOLVED: To provide a functional resin substrate excellent in durability and having water repellency and photocatalytic activity. SOLUTION: A resin substrate, which is provided with the hydrolyzable SiX<SB>4</SB>(wherein X is a hydrolyzable functional group) chemically bonded to a hydrolyzable resin layer, is installed on the surface of a resin substrate 10 having a hydrolyzable resin layer overlying its surface and a layer of a hydrolyzable TiY<SB>4</SB>or RnTiY<SB>4-n</SB>(wherein n is an integer of 1-3, R is an alkyl group or a fluoroalkyl group and Y is a hydrolyzable functional group) chemically bonded the SiX<SB>4</SB>layer is provided on the resin substrate. By this method, the hydrolyzable silane compound (wherein X is a hydrolyzable functional group) is chemically strongly bonded to a hydrolyzed (activated) resin molecule to mutually fix resin molecules through a silane compound SiX<SB>4</SB>layer to stabilize a resin surface.
