1. An inductor comprising:
- a body, including;
a coil support layer,a conductive coil on a surface of the coil support layer,a first insulating layer between adjacent turns of the conductive coil and extending higher than an upper surface of the conductive coil,a second insulating layer covering the first insulating layer and the conductive coil, anda cover layer comprising magnetic material and covering the second insulating layer; and
external electrodes on respective end surfaces of the body,wherein a gap disposed between the adjacent turns of the conductive coil is substantially filled with the first insulating layer, andwherein the second insulating layer extends to cover at least one of an outermost side end portion of the first insulating layer and an innermost side end portion of the first insulating layer in a length direction of the body.

Abstract
An inductor may include: a body, and a first and a second external electrode formed on end surfaces of the body. The body may include a coil support layer, a conductive coil formed on at least one surface of the coil support layer, a lamination part formed in a gap of the conductive coil and on an upper surface thereof, an insulating coating part formed to enclose an overall surface of the conductive coil on which the lamination part is formed, and upper and lower cover layers covering the overall surface of the conductive coil on which the insulating coating part is formed.
