PROBLEM TO BE SOLVED: To provide a circulator with excellent mass-productivity without the need for a dielectric spacer tube, defective assembly with mis-alignment while providing a circulator characteristics close to that of a circulator with an ideal structure with excellent reproducibility stably. SOLUTION: Stepped parts 7, 9 with a step equal to the plate thickness of circulator ferrite plates 3, 5 are formed to both upper and lower sides at a tip of a mode suppressor connected to a dielectric strip line member. Upper/ lower circulator ferrite plates 3, 5 are engaged respectively with the upper/lower stepped parts 7, 9 and even in the form of the upper/lower circulator ferrite plates 3, 5 supported by the mode suppressor 1, the vertical interval of the upper/lower circulator ferrite plates 3, 5 is specified by the stepped parts 7, 9. |
