PURPOSE: An anode structure of a magnetron is provided to stabilize a thermal characteristic of a resonant element and to improve a thermal characteristic of a magnetron, by connecting an end part of a rod adhered to an inside wall of an anode cylinder to a ring-typed disc, and by fixing the disc to the inside wall of the anode cylinder. CONSTITUTION: An anode structure of a magnetron comprises a cylindrical anode cylinder(4), a plurality of quadrangular rods(5) and an interdigital resonant structure. The plurality of quadrangular rods are disposed radially with an axial direction of the anode cylinder as a center while separated from the anode cylinder in the anode cylinder, and stands in the same direction as the axial direction of the anode cylinder. The interdigital resonant structure is fixedly installed to an inside of the anode cylinder by alternatively connecting top and bottom ends of the rod. A ring-type metal disc(11, 11A) is connected to end parts in the inside of the anode cylinder of the rod, so as to prevent the rod from being thermally transformed by overheating. The metal disc is fixedly installed in the inside of the anode cylinder.
