PROBLEM TO BE SOLVED: To provide an inexpensive non-reciprocal circuit element which has satisfactory productivity. SOLUTION: This non-reciprocal circuit element is provided with a ferrite member 4; a multilayer substrate 5 having first, second, third center conductors 6, 7 and 8 which are insulated from one another in a state of crossing at a predetermined angle via a dielectric layer; a magnet 2; and a second yoke 3 forming a magnetically closed circuit in cooperation with a first yoke 1. Ground portions 6b, 7b and 8b of the center conductors 6, 7 and 8 are bent to the bottom plate 3a side of the second yoke 3 together with a bending portion 5b of the multilayer substrate 5, and the ground portions 6b, 7b and 8b are soldered to the bottom plate 3a and grounded. Thus, a conventional dielectric substrate is not required, and an inexpensive product having the smaller number of parts and satisfactory productivity can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI
