PURPOSE: A waveguide of a magic T structure is provided to use in a small space so as to enhance application. CONSTITUTION: A waveguide of a magic T structure comprises a tube type T waveguide(20a) including a first and a second terminals(21,22) coupled to each other and a third terminal(23) coupled to the first and the second terminals(21,22) perpendicularly, and a tube type L waveguide(20b) including a fourth terminal(24). The L waveguide(20b) is started from a cross point of the T waveguide(20a) and is arranged in parallel to the waveguide of the first and the second terminals(21,22). The T waveguide(20a) and the L waveguide(20b) include an integrated waveguide duct(25), a first cover(26) for covering the T waveguide(20a) of the waveguide duct(25), and a second cover(27) for covering the L waveguide(20b) of the waveguide duct(25).
