PROBLEM TO BE SOLVED: To provide a hollow waveguide that can vary a transmissible wavelength band of light and an output intensity during the use, and also to provide its application device. SOLUTION: The hollow waveguide 1 has a metallic layer 3 composed of gold, silver, copper, aluminum, etc. formed on the interior surface of a glass capillary tube 2, and a dielectric layer 4 composed of an inorganic or organic resin formed on the inner surface of the metallic layer 3. The dielectric layer 4 is formed in such a manner that the thickness is different depending on the circumferential directionθ. As a result, since the transmission characteristic varies by selecting a thickness of the light-transmitting dielectric layer, the transmissible wavelength band of light and the output intensity can be varied during the use.
