Abstract
A magnetic resonance type isolator includes a ferrite; a connection conductor that is arranged on the ferrite and includes a first port, a second port and a third port; a permanent magnet that applies a direct current magnetic field to the ferrite; an inductor that defines a reactance element; and capacitors that define an impedance matching circuit. A main line arranged between the first port and the second port of the connection conductor does not resonate, an end portion of a sub-line that branches from the main line serves as the third port, and a wave reflected from the sub-line is modulated so that its phase is shifted by 90° or about 90° at an intersection of the connection conductor. The inductor is connected to the third port and the capacitors are connected to the first and second ports, respectively.
