A coil component includes a first core having a leg portion, a second core joined to the first core with the leg portion therebetween, and a magnet disposed between the leg portion and the second core. Movement of the magnet in a first direction intersecting a direction in which the first core and the second core face each other is at least restricted by an uneven structure provided on a junction surface between the magnet and at least one of the first core and the second core.
