Abstract: An inductor includes a body including a coil, and a support member and external electrodes disposed on an outer surface of the body. The coil may include first and second coils, wherein the first coil does not coincide with a coil mirror-symmetric to the second coil, based on one surface of the body. This is due to the fact that exposure positions of lead portions of the first and second coils exposed to the outer surface of the body are different from each other.
