。[Claims for Utility Model Registration] A metal impedance transformer 5 is placed at the center of the part where the waveguides provided in the metal casings 1 and 2 are branched into three directions in order to widen the usable band. ,
A ferrite column 7 is placed on the transformer via a thin dielectric plate 61 with a low dielectric constant, and a thin dielectric plate 62 with a low dielectric constant is placed on top of the ferrite column to form a waveguide branch. 3, which is magnetized by applying a direct current magnetic field to the ferrite column from the outside and has a characteristic of low transmission loss in one direction and high transmission loss in the opposite direction, a convex with a small diameter on the lower surface of the impedance transformer. A hole 4 having a diameter slightly larger than the diameter of the convex part 51 is provided at the center of the waveguide branch part 3 of the lower housing 2 to which the impedance transformer is to be attached. A waveguide circulator characterized in that a convex portion 51 on the lower surface of the impedance transformer 5 is inserted into the hole 4 of the branch portion 3 and fixed.
