Abstract

In this non-reciprocal circuit element, a box-like member 2 for accommodating a ferrite member 7 is formed of a second yoke 3 and an insulating resin body 5. A ground terminal 3e embedded in the resin body 5 has a coupling section 3c coupled to a bottom plate 3a and a bent tongue piece 3d extending along the external wall of the side wall 5b of the resin body 5. An L-shaped input / output terminal 4 embedded in the resin body 5 has a bottom 4a in the same plane state as the bottom plate 3a, and a bent side 4b extending along the external surface of the side wall 5b of the resin body 5. Thus, the bottom piece 4a of the input / output terminal 4 is in the same surface state as the bottom plate 3a of the second yoke 3, the thickness of the bottom wall of the box-like member 2 can be reduced, and a thin element can be obtained.
