PURPOSE: A magnetron is provided to prevent interference from a wireless LAN by determining separation distance from a strap by modifying the shape of a vane. CONSTITUTION: An anode cylinder(2) is arranged in the inner side of a yoke in a cylindrical form. A plurality of vanes(3) are radially arranged inside the anode cylinder. The separation distance between the vane and the strap is determined according to the oscillation frequency of a superhigh frequency. Two straps(4,5) are sequentially connected to the upper and lower part of the leading end side of the vane. The two straps form the vane and a resonance circuit.
