| 摘要 |
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.
