PROBLEM TO BE SOLVED: To provide an easier and more economic method of obtaining a final product easy to be handled. SOLUTION: A conductive pattern comprising an electrode 2 and a conductive route 4 and formed from a transparent conductive oxide such as ITO is formed on one surface of a transparent substrate 3 made of sapphire or toughened glass, and coated with a first layer 5 of a transparent dielectric having a low refractive index such as MgF<SB>2</SB>or LiF<SB>2</SB>, and furthermore, coated with a second layer 7 of another transparent dielectric having a high refractive index such as Al<SB>2</SB>O<SB>3</SB>, Ta<SB>2</SB>O<SB>5</SB>or DLC.
