Abstract: Disclosed herein is a coil component that includes first and second substrates, a first coil pattern formed on one surface of the first substrate, a second coil pattern formed on one surface of the second substrate, a first terminal electrode connected to one end of the first coil pattern and protruding from the first substrate, and a second terminal electrode connected to one end of the second coil pattern and protruding from the second substrate. The first and second substrates are laminated such that the first and second terminal electrodes overlap each other and are connected to each other.
