PROBLEM TO BE SOLVED: To obtain a non-reciprocal circuit element, that can prevent a part of resin from covering the bottom faces of external terminals nor flowing in notches in junctions of a lead frame, without impairing the size reduction or height reduction of the element at insertion-molding. SOLUTION: This non-reciprocal circuit element has external input/output terminals 5 and external grounding terminals 6, both of which are insert-molded so that the terminals 5 and 6 protrude from the bottom face of a resin case 1 at the molding of the case 1. On the bottom face of the case 1, recessed sections 2 surrounding the protruded sections of the electrodes 5 and 6 are formed to absorb part of a resin at insert-molding of the terminals 5 and 6, so as to prevent the resin from covering the bottom faces of the terminals 5 and 6.
