PROBLEM TO BE SOLVED: To provide a waveguide converter with excellent propagation characteristic by reducing mutual interference among adjacent waveguide paths. SOLUTION: A second groove 10 is provided to a joining face between a barrier 9 formed between waveguide paths 7 and a first metallic plate and the depth of the second groove 10 is selected to be about an odd number multiple of 1/4 of a free space propagation wavelength for a high frequency signal.
