PROBLEM TO BE SOLVED: To provide a two-terminal pair isolator with a small size, a low profile, and a small loss the bandwidth of an insertion loss of which ranges over a broadband. SOLUTION: The two-terminal pair isolator is placed in the vicinity of the center of a ferrite to which a static magnetic field is applied is characterized by that first and second center conductors are crossed in an electrically isolated state, one-side ends of the first and second conductors respectively act like first and second input output terminals, the other ends are connected to a common part, a first matching capacitor is connected between the first input output terminals and the common part, a second matching capacitor is connected between the second input output terminals and the common part, a resistive element is connected between the first and second input output terminals, and a cross angle between a center axis of the first center conductor and a center axis of the second center conductor is selected within a range from 40-degrees to 80-degrees.
