PROBLEM TO BE SOLVED: To provide a nonreciprocal circuit element with excellent connection reliability wherein electrode patterns formed to a lamination board are easily connected to a terminal part and a magnetic yoke part without causing a solder bridge even when an interval between the terminal part and the magnetic yoke part is narrow. SOLUTION: In the nonreciprocal circuit element provided with: a center conductor assembly 20 formed by arranging a plurality of center conductors to a ferrimagnetic material; the plate-like lamination board 15 in which a plurality of capacitive elements for configuring a resonance circuit with the center conductors are formed; an almost square box shaped lower case 30 for housing the lamination board 15; a permanent magnet 2 for applying a DC magnetic field to the ferrimagnetic material; and an upper case 1 to which the permanent magnet 2 is located, it is characterized in that solder is pooled to the terminal part and a recess of a magnetic yoke lower side part and the solder is used to connect the electrode patterns formed to the outer surface of the lamination board 15 to the terminal part and the magnetic yoke part.
