PROBLEM TO BE SOLVED: To improve the insertion loss and isolation characteristics of a high frequency signal in a higher frequency band and a wider band, to improve the accuracy of relational positions of a mode suppressor and a ferrite board, to hardly cause the center deviation of two ferrite boards by facilitating the reassemblage of a circulator, to stably provide circulator characteristics with high reproducibility, to facilitate production and to improve mass-productivity. SOLUTION: An impedance matching member 5 having a dielectric constant different from those of intermediate dielectric line members 4d-4f and dielectric lines 4a-4c is installed at the top end of a mode suppressor 1. |
