PROBLEM TO BE SOLVED: To provide a nonreciprocal circuit element with a low profile at low cost and having excellent assembling performance. SOLUTION: The nonreciprocal circuit element is provided with: a first yoke 1; a magnet 3 located to a lower side of an upper plate 1a; a second yoke 4 for configuring a magnetic closed circuit together with the first yoke 1; a ferrite flat plate member 8 arranged between a bottom plate 4a and the magnet 3; first, second, and third center conductors 10, 11, 12 formed on the ferrite member 8 and arranged in a way that parts of which are in crossing via a dielectric 9 in vertical directions; capacitors C1, C2, C3 connected to the center conductors 10, 11, 12 and formed on the ferrite member 8, and since the thin film or thick film capacitors C1, C2, C3 are formed on the upper face of the ferrite member 8, chip capacitors unlike prior arts are not required, the assembling man-hours can be decreased, the assembling performance can be improved, and the nonreciprocal circuit element can be formed at low cost.
