Abstract: A coil component includes a mounting surface that is a side mounted on a mounting board and a detecting surface that is a side generating a magnetic field to detect a distance from a detected conductor. The coil component has a coil conductor formed into a spiral shape, and a magnetic resin disposed on the mounting surface side of the coil conductor without being disposed on the detecting surface side of the coil conductor.
