A coil component includes a body, an internal insulating layer disposed in the body, and a coil portion disposed on the internal insulating layer. The coil portion includes first and second coil patterns disposed on opposing surfaces of the internal insulating layer, respectively, first main and first auxiliary lead-out portions extending from the first coil pattern and respectively exposed to a front surface and one side surface of the body connected to each other, and second main and second auxiliary lead-out portions extending from the second coil pattern and respectively exposed to a rear surface and another side surface of the body connected to each other.

Coil component

An inductor includes a body including a substrate, a coil portion, including a top coil and a bottom coil disposed on one surface and the other surface of the substrate, respectively, and an encapsulation portion encapsulating the substrate and the coil portion, a first terminal electrode, disposed on a bottom surface of the body and connected to the top coil, and a second terminal electrode disposed on the bottom surface of the body and connected to the bottom coil, a third terminal electrode disposed between the first and second terminal electrodes and disposed on the bottom surface of the body, and a shielding layer disposed to cover the body. The shielding layer is connected to the third terminal electrode.

Inductor

An apparatus for checking an inductor includes a detector outputting a detection signal including information corresponding to a parallel resistance component of a checking target inductor; and a determiner receiving the detection signal and determining whether the checking target inductor is satisfactory based on a magnitude of the parallel resistance component.
