PURPOSE:To avoid giving an evil effect to illumination, etc., by providing a linear conductor to a transparent substrate with a space which is small sufficiently compared with the wavelength of an electric wave to be reflected in order to transmit visible light beams and to reflect an electric wave of an ultra- high frequency. CONSTITUTION:A linear conductor 4 is formed on a transparent substrate 3 of polyester, etc. by means of a metallic thin film, and an adhesive mass 5 is provided at the opposite side to the conductor 4. Thus the substrate 3 can be stuck to the window glass, etc. An electric wave of an ultra-high frequency is reflected by the mesh type conductor 4 while a visible light beam is transmitted. It is desirable to use a thin film of a good conductor like copper, aluminum, nickel, etc. to produce the conductor 4. |
