<P>PROBLEM TO BE SOLVED: To provide a non-reciprocal circuit element which minimizes the inductance component produced in a connection line provided on a circuit board and facilitates matching of the input/output impedances, and also to provide a composite electronic component. Ž<P>SOLUTION: A ferrite 32 having first and second central electrodes arranged to intersect in a state insulated electrically from each other, and a ferrite-magnet element 30 where the opposite major surfaces of the ferrite 32 are sandwiched by a pair of permanent magnets 41 so that a DC magnetic field is applied to the ferrite 32, are mounted on the surface of a circuit board 20 in a non-reciprocal circuit element. On the surface of the circuit board 20, chip type matching circuit elements C1, C2, CS1, CS2, CA1, and R are arranged in close proximity to the ferrite-magnet element 30. The chip type matching circuit element C1 is preferably arranged in close proximity to the side surface of the ferrite-magnet element 30. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
