Abstract

There is provided a coil electronic component including: a main body having a laminated structure formed using a plurality of conductor patterns disposed therein, and including an insulating layer disposed between the plurality of conductor patterns; and an external electrode disposed outside the main body. A part of the plurality of conductor patterns includes a coil pattern and an extraction pattern connecting the coil pattern to the external electrode, and the extraction pattern includes a first metal layer and a second metal layer disposed on the first metal layer. a metal layer, and the pore density of the first metal layer is higher than the pore density of the second metal layer.

Description

[0001] This application claims the priority right of korea patent application No. 10-2019-0044388 filed at the Korean Intellectual Property Office on April 16, 2019, and the disclosure of the Korean patent application is fully incorporated herein by reference. Technical field [0002] The present disclosure relates to a coil electronic component. Background [0003] A coil electronic component or inductor is a component that is included in an electronic circuit along with resistors and capacitors. Inductors can be formed by winding or printing coils on a ferrite core and forming electrodes at both ends, and can be used as a component for noise removal or as a component for LC resonant circuits. Depending on the form of the coil, there may be various types of inductors, such as multilayer inductors, wire-wound inductors, thin-film inductors and the like. [0004] Multilayer inductors can be manufactured by layering multiple coil layers, pressing sealed coil layers, and sintering co...
