In this embodiment, reference numeral 3 denotes a copper base material serving as a waveguide, and the base material 3 is subjected to metal working to form a groove 4 serving as a waveguide. The groove 4 is filled with a wax 5 made of paraffin that can be melted at a low temperature of about 90 ° C., and a silver powder is applied to the surface of the wax 5 or a metal coating is applied by zinc substitution plating, and then the base material is formed. 3 and copper on the wax 5 by electroforming.
A metal layer 2 such as nickel is deposited to a required thickness ( for example, 2 mm in the embodiment). The metal layer 2 deposited by this electroforming becomes a part of the waveguide. Next, by heating to about 90 ° C., the wax 5 filled in the groove 4 is dissolved, and the wax 5 is poured out from the groove 4 and removed, so that the base material 3 and the metal layer 2 deposited by electroforming can be used. A wave tube 10 is obtained.
