Abstract
An isolator has a magnetic core of a plate shape placed within a direct current magnetic field and having an upper face perpendicular to the direction of the direct current magnetic field, and first to third central conductors overlapping other at an equal angle interval approximately in the central portion of the upper face of the magnetic core, and having one end connected to the ground. The other end of the first central conductor is an input terminal, and the other end of the second central conductor is an output terminal. At least the third central conductor is constructed by two parallel band-shaped conductors. One end of one band-shaped conductor is connected to the ground by a first resistor and a first capacitor. The other end of the other band-shaped conductor is connected to the ground by a second resistor and a second capacitor. The capacity value of the first capacitor and the capacity value of the second capacitor are different from each other.
