Claims

[Scope of Claim for Utility Model Registration] (1) A ferrite assembly consisting of a plurality of central conductors that intersect in an electrically insulated state and ferrites facing each other is housed in a case body made of a magnetic material, and a case lid is attached to the case body. In the non-reciprocal circuit element, a slit is formed in the side wall of either the case body or the case lid, and extends from the opening edge in the direction in which the case lid is attached. A wider engagement hole is formed at the tip of the case lid, and a protrusion is formed on the other side wall to engage the engagement hole after passing through the slit when the case lid is attached. Non-reciprocal circuit element. (2) A resin guide that has recesses cut out in the side walls of the case body and the case lid, and has engaging claws integrally formed on the edges of the recesses to position the ferrite assembly within the case body. 1. A non-reciprocal circuit element characterized in that a plate is disposed, a fitting portion that fits into each of the recesses is integrally formed on the guide plate, and the engaging claw portion is engaged with the fitting portion.
