Abstract

The present invention provides a coil assembly comprising: a body having one surface and one end surface and another end surface, the one end surface and the other end surface being connected to the one surface and opposed to each other, respectively; a support substrate embedded in the main body; and a coil part provided on the support substrate and including a first lead-out pattern and a secondlead-out pattern respectively exposed from a surface of the main body. The first lead-out pattern is exposed from the one surface of the body and the one end surface of the body. The second lead-outpattern is exposed from the one surface of the body and the other end surface of the body. The body includes an anchor portion provided in each of the first lead-out pattern and the second lead-out pattern.

Description

[0001] This application claims the benefit of priority to Korean Patent Application No. 10-2019-0057062 filed with the Korean Intellectual Property Office on May 15, 2019, the entire disclosure of which is incorporated by reference for all purposes at this. technical field [0002] The present disclosure relates to a coil assembly. Background technique [0003] An inductor (a coil component) is a representative passive electronic component used in electronic devices along with resistors and capacitors. [0004] As electronic devices have higher performance and smaller sizes, the number of electronic components used in the electronic devices has increased while their sizes have decreased. [0005] In the case of a general film type inductor, since the body includes metal powder as a conductor, an insulating film is interposed between the coil and the body for electrically insulating the coil and the body. [0006] On the other hand, since the relative area occupied by the l...
