Abstract
A method of producing a chip inductor including the steps of inserting a conductive wire made of a metallic wire into a metallic mold, supporting both end portions of the conductive wire on support portions provided on inner surfaces of the metallic mold so as to position the conductive wire in the approximate center portion of the metallic mold, casting magnetic ceramic slurry into the metallic mold, molding the ceramic slurry case in the metallic mold by wet pressing to obtain a molding body having the conductive wire embedded therein, firing the molding body, and forming external electrodes on both end surfaces of the fired magnetic core such that the external electrodes are connected to both end portions of the conductive wire.
