Abstract:
1. A non-reciprocal circuit element comprising: a flat plate-shaped ferrite part; and first, second, and third central conductors disposed over a plurality of surfaces of the ferrite part, wherein the first, second, and third central conductors on a top surface of the ferrite part are stacked on one another with first dielectric parts disposed therebetween, and portions of the first, second, and third central conductors intersect vertically, wherein the first, second, and third central conductors and the first dielectric parts are formed of multilayer thin films or thick films, wherein each of the first, second, and third central conductors includes a first extended portion which extends from one end of the corresponding central conductor and which is disposed on a side surface of the ferrite part and a second extended portion which extends from another end of the corresponding central conductor and which is disposed on the side surface of the ferrite portion, and wherein adjacent first and second extended portions facing each other with a second dielectric part, which is formed of a thin film or a thick film, disposed therebetween form a capacitor.
