Abstract
A variable inductor includes a conductor and an electroconductive member. The conductor has a coil and a pair of terminals electrically connected with the coil. The electroconductive member is movable closer to and farther away from the coil. The inductance between the terminals becomes smaller as the distance between the coil and the electroconductive member becomes shorter. Conversely, the inductance between the terminals becomes larger as the distance between the coil and the electroconductive member becomes longer.
