Abstract
A variable inductor includes an insulating substrate (1), a thermally softenable spiral coil (2) provided on the insulating substrate (1), and a pair of input/output terminals (3, 4) each connected electrically to a respective end of the coil (2). Preferably, the coil (2) is made from a non-crystalline thin film metallic glass which softens in a supercooled liquid phase.
