POWER INDUCTOR AND MANUFACTURING METHOD THEREOF

摘要

Disclosed herein is a power inductor including: an opening part penetrating through the insulating layer; an upper coil electrode pattern formed on an upper surface of the insulating layer and having a form in which it is wound around the opening part; a lower coil electrode pattern formed on a lower surface of the insulating layer and having a form in which it is wound around the opening part; and metal layers plated on a surface of the innermost pattern of the upper coil electrode pattern and a surface of the innermost pattern of the lower coil electrode pattern, wherein the metal layers plated on the surfaces of the innermost patterns of the upper and lower coil electrode patterns are extended to an inner wall of the opening part to thereby be connected to each other.
