Abstract: A micro-channel chip can be coated uniformly with a thin inorganic oxide film and can prevent an ionic hydrophobic substance from adsorbing through a surface of an inorganic oxide film. In the micro-channel chip, surfaces of inner walls of through-holes in an upper plate member and a channel of a lower plate member are entirely coated with a SiO 2 film. The SiO 2 film is formed of two layers, namely a bottom layer that contains a high content of carbon atoms and is formed in a part that contacts a resin substrate, and a surface layer that contains nearly zero content of carbon atoms and t is formed in a part that is exposed on the surface of a channel.

Abstract: An optical element which includes an optical block having a cavity part formed on an optical path and an inclined face formed in an internal face of the cavity part at a prescribed inclining angle with respect to a traveling direction of light. Multilayer films of the same structure are formed at least on the internal face of the cavity part and on an interface between a light incident end and/or emission end of the optical block and outside. The multilayer film formed on the incline face in the internal face of the cavity part has at least a wavelength selecting function for light to be used.

Abstract: There is provided an optical element which can achieve more reduction in the number of components, downsizing, low cost, and an improvement in the mass-productivity while maintaining an excellent optical property. The optical element comprises: an optical block having a cavity part formed on an optical path and an inclined face formed in an internal face of the cavity part at a prescribed inclining angle with respect to a traveling direction of light, wherein multilayer films of the same structure are formed at least on the internal face of the cavity part and on an interface between light incident end and/or emission end of the optical block and outside. The multilayer film formed on the inclined face in the internal face of the cavity part has at least a wavelength selecting function for light to be used, and the multilayer film formed on other face than the inclined face has an antireflective function for light to be used.

Abstract: A method of manufacturing a decorative panel having an embossed surface and different degrees of glass corresponding to a pattern, thereby producing a stereoscopic aspect, i.e., the impression of relief and solidity.
