PROBLEM TO BE SOLVED: To obtain a waveguide switch capable of achieving low loss and broad-band characteristics. SOLUTION: The waveguide switch has a rectangular waveguide with a lower conductor 21 and an upper conductor 22, a conductor rod 30 connecting a lower surface to the lower conductor 21 of the rectangular waveguide and being fitted in the rectangular waveguide and having a length from the lower surface longer than a quarter wavelength and a separating section 40 separating the conductor rod 30 from the upper conductor 22 for the rectangular waveguide. The waveguide switch further has a conductor wall 50 having one end connected to the end of the upper conductor 22 opposed to the separating section 40 and having the length L of an approximately quarter wavelength so as to have a specified interval while being opposed to the conductor rod 30 fitted in the rectangular waveguide and switching elements 61 to 64 connecting one to the conductor rod 30 and connecting the other to the upper conductor 22 and changing over an electrical connection between the conductor rod 30 and the upper conductor 22.
