PROBLEM TO BE SOLVED: To provide a high-frequency module provided with a non-reciprocal circuit element which has high productivity, and is inexpensive and small. SOLUTION: This high-frequency circuit module provided with a non-reciprocating circuit element is provided with a circuit board 1 consisting of a multilayer board, and a high-frequency circuit element K including a non-reciprocating circuit element K1 provided on this circuit board 1. The element K1 has a lower yoke 5 consisting of a magnetic material film formed in a housing unit 2 of the circuit board 1; a ferrite member 6 housed in a housing unit 2; first, second and third center conductors 8, 9 and 10 disposed on the ferrite member 6 via a dielectric 7; a magnet 11; and an upper yoke 12 disposed so as to cover the top of this magnet 11 and the housing unit 12. Since the lower yoke 5 is formed of the magnetic material film, the yoke 5 has the smaller number of parts than that of a conventional yoke, has high productivity and is inexpensive, and the non-reciprocal circuit element itself can be miniaturized in a thickness direction.
