PROBLEM TO BE SOLVED: To provide a low cost nonreciprocal circuit module which realizes a broadband, using a nonreciprocal circuit element having a basic structure as it is. SOLUTION: The module comprises a nonreciprocal circuit element 1 and a circuit board 9. The element 1 comprises a magnetic rotator 6, capacitors C1-C3 and a permanent magnet 8. The rotator 6 comprises a soft magnetic base 60 and a plurality of center conductors 64-66 combined with the soft magnetic base 60 and the capacitors C1-C3 connected thereto. The permanent magnet 8 applies a DC magnetic field to the rotator 6. The circuit board 9 comprises module terminals 91-93 and LC circuits LC1, LC2. The circuit element 1 is mounted on one surface of the board 9. Terminals 17, 20 of the circuit element 1 are connected to the module terminals 91, 92 through the LC circuits LC1, LC2.
