Abstract

An inductor includes: a body including a coil and a magnetic material, and external electrodes disposed on an outer surface of the body. The coil is supported by a support member, and the support member may also support an insulating wall including an open-hole pattern having a shape corresponding to a pattern of the coil. An insulating ribbon formed so that a length thereof is greater than a width thereof may be additionally disposed on at least a portion of an upper surface of the insulating wall.

Description

[0001] This application claims the benefit of priority from Korean Patent Application No. 10-2016-0139394 filed in the Korean Intellectual Property Office on October 25, 2016, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates to an inductor, and more particularly, to a film-type power inductor advantageous for small size and high inductance. Background technique [0003] According to the development of information technology (IT), miniaturization and thinning of devices have been accelerated, and market demand for small and thin devices has increased. [0004] The following Patent Document 1 provides a power inductor including: a substrate having a via hole so as to be suitable for meeting the demands of this technical trend; and coils provided on both surfaces of the substrate and electrically connected to each other through the via hole of the substrate. connected to provide an inductor comp...
