<p>The present invention relates to an inductor having a self-focusing structure, a method for manufacturing the same, and a hybrid inductor comprising the same and, more particularly, to an inductor, a method for manufacturing the same, and a hybrid inductor comprising the same, the inductor comprising: a core assembly comprising a core having a core body of a predetermined length and a coil wound around the core body; and a focusing cover containing a permeable substance, the focusing cover being formed such that, after the core assembly is inserted therein, the focusing cover surrounds at least a part of the coil at the outer periphery of the core assembly, thereby limiting external diffusion of lines of magnetic force generated by a current flow through the coil and focusing the lines of magnetic force. The present invention is advantageous in that, by focusing lines of magnetic force through the focusing cover, the efficiency of a choke transformer or another type of transformer is improved further; an air gap can be formed through a gap flange; and the simple structure reduces manufacturing costs.</p> |
