PURPOSE: An output unit structure of a magnetron is provided to achieve improved capability of attenuating the third harmonic wave by permitting the vent pipe of the magnetron to be spaced apart from the top of the antenna ceramic. CONSTITUTION: An output unit structure comprises a support(100-1) for fixing an antenna cap(1); an antenna ceramic(3) coupled to the support; a vent pipe(100) supported by the support, and which has a top arranged in the lower portion of the antenna cap and a bottom spaced apart from the top of the antenna ceramic; and an antenna feeder(4) assembled to the inner wall of the vent pipe so as to radiate microwaves to the outside.
