<P>PROBLEM TO BE SOLVED: To provide a waveguide circulator capable of preventing an arcing phenomenon even if heat generation of a ferrite causes an increase in temperature, and preventing the deterioration in microwave characteristics. Ž<P>SOLUTION: The waveguide circulator has a structure in which two ferrites are arranged oppositely to upper and lower sides in a height direction perpendicular to the a predetermined plane at a branched position of a waveguide forming a substantial Y-shape by the rectangular waveguide provided horizontally on the predetermined plane and extending in three different directions from the branched position. In the waveguide circulator, an extending part extending in the height direction in the vicinity of the waveguide branching position is formed, and an impedance reduced by widening the distance between the ferrites is compensated.
