Abstract

PURPOSE:To stabilize performance as well as miniaturization and price reduction by providing metal fittings for fixation while employing a fixed assembling method. CONSTITUTION:On soft magnetic body 16, shielding plate 12 in which two ferrite cores 13a and 13b and three center conductors 14a-14c have been contained is fixed by screws 11a and 11c and washers 15a and 15c with dielectrics 15a-15c interposed, and on it, permanent magnet 8 is fixed with dielectrics 9a-9c interposed. Further, metal fitting 21 is placed on permanent magnet 8 covering it and screws are inserted into its fitting holes 17a and 17b to fix it on heat sink 20 tightly. The abovementioned formation can miniaturize and price low a circulator and isolator and since magnet 8 is fixed tightly, shock resistance can be improved to stabilize the performance.
