A variable inductor includes a spiral inductor, a loop conductor, and a switch for opening or short-circuiting an end of the loop conductor. The loop conductor is formed in a direction perpendicular to the spiral inductor and is used for adjusting the inductance value of the spiral inductor by opening or short-circuiting the end of the loop conductor by the switch.
