Provided is a coil component that includes: a coil pattern provided on a substrate and including a plurality of separated end sections that are separated from each other with a gap in between; and a conduction member that allows a selective electrical conduction between the respective separated end sections. The selective electrical conduction causes a change in the number of turns of the coil pattern. Every section in the coil pattern configures a part of the coil component, irrespective of the number of turns.
