Abstract
An irreversible circuit element includes a planar ferrite member, a plurality of dielectrics which are formed on the ferrite member in a laminated manner and are made of an insulation material, and the first, the second and the third center conductors which are formed on surfaces different in a vertical direction while sandwiching the dielectrics therebetween and have portions thereof to cross each other in the vertical direction. Accordingly, it is possible to reduce the thickness in the vertical direction so that a thin irreversible circuit element can be provided.
