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 SiOfilm. The SiOfilm 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.

Micro-channel chip and micro-analysis system

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.
