PROBLEM TO BE SOLVED: To provide a two-center conductor type irreversible device having smaller insertion loss and a larger bandwidth. SOLUTION: In this two-center conductor type irreversible device, first and second center conductors are provided in proximity to a thin ferrite plate so that they cross each other in an electrically insulated state. A magnetostatic field is applied to the thin ferrite plate, and one end of the first center conductor is taken as a first input/output terminal and the other end of the first center conductor is taken as a second input/output terminal. A first impedance element is connected between one end of the second center conductor and the first input/output terminal, and a second impedance element is connected between the one end of the second center conductor and the second input/output terminal. A third impedance element is connected between the one end and the other end of the first center conductor. The other end of the second center conductor is connected to a common portion, and a fourth impedance element is connected between the one end of the second center conductor and the common portion.
