PROBLEM TO BE SOLVED: To increase the variation of inductance while preventing increase of series resistance in a variable inductor. SOLUTION: This variable inductor includes: a first inductor having both ends connected to a first terminal and a second terminal; a second inductor having both ends connected to the first terminal and the second terminal; a first node formed on the first inductor; a second node arranged on the second inductor; and a switch element for bringing the first node and the second node into a conduction state to each other or into a non-conduction state from each other.
