Claims (1)

[Scope of utility model registration request] Three sets of central conductors, each consisting of two nearly parallel conductors, each half of which is formed on the front and back surfaces of an insulating substrate, are connected together through a through hole in the center. In a non-reciprocal circuit element comprising a substrate-like center conductor formed on an insulating substrate so as to form an angle of approximately 120 degrees with each other and each conductor intersects with the insulating substrate in between, each center of the substrate center conductor A non-reciprocal circuit element characterized in that the distance between two conductors constituting the conductor is wider near the center than near both ends of the conductor.
