Claims

[Scope of utility model registration request]

A central conductor section consisting of at least one ferrite core and at least three center conductors, and a permanent magnet that applies a DC magnetic field to the ferrite core are surrounded by a case, with a grounding conductor film on one side and the grounding conductor on the other side. The one side of the insulating substrate on which a grounding conductor film electrically connected to the membrane, at least three capacitance forming conductor films, and a resistance film are formed is joined to the case, and the center conductor protruding from the opening of the case is connected to the case. A lumped constant isolator, characterized in that it is connected to the capacitance forming conductive film of the insulating substrate.
