PROBLEM TO BE SOLVED: To provide a non-reciprocal circuit element capable of independently adjusting each of input impedance and output impedance by a simple method without providing an impedance conversion circuit in a two-port isolator. SOLUTION: In the two-port isolator having the input port, the output port, and a ground port; a first center conductor and/or a second center conductor which are disposed in ferrite for a microwave are formed so that their widths may differ in a portion excepting a crossing section, thereby performing impedance adjustment.
