PROBLEM TO BE SOLVED: To provide a nonreciprocal circuit device in which an insertion loss is reduced and isolation is excellent. SOLUTION: The nonreciprocal circuit device is provided with a plate-like ferrite member 4 and first, second and third central conductors 5, 6 and 7 positioned on the ferrite member 4 and in the central conductors 5, 6 and 7, second conductors 5e, 6e and 7e are positioned on the ferrite member 4 while positioning first conductors 5d, 6d and 7d for input or for output in a notched portion 4b of the ferrite member 4 such that, when magnetic flux is passed through a V-shaped extension part 4a as a magnetic path G, generation of an electric current is reduced and transmission of energy is enlarged in the first conductor positioned therebetween. As a result, the insertion loss is reduced and the isolation becomes excellent. COPYRIGHT: (C)2004,JPO
