<p>Provided are a nonreciprocal circuit element and a wireless communication terminal device with which it is possible to increase bandwidth. A nonreciprocal circuit element (circulator) is provided with: a magnetic core (11); a permanent magnet for applying a direct-current field to the magnetic core (11); a plurality of center conductors (X1, X2, X3) disposed on the magnetic core (11) insulated from one another and intersecting one another at a predetermined angle; and auxiliary conductors (Y1, Y2, Y3) disposed on the magnetic core (11) adjacent to at least one center conductor among the center conductors (X1, X2, X3). The auxiliary conductors (Y1, Y2, Y3) are coupled to the adjacent center conductors (X1, X2, X3) via at least the magnetic core (11) by means of magnetic-field coupling.</p> |
