Abstract
A variable inductor element has a substrate, a first inductor element which is fixedly arranged on the substrate, a second inductor element which is supported by the substrate, is magnetically coupled with the first inductor element and variably control a mutual conductance with the first inductor element, and at least one piezoelectric actuator pair which torsionally drives the second inductor element.

A variable inductor element, comprising:
- a substrate on which a concave portion is formed;
- a first inductor element, at least a portion of the first inductor element being capable of being arranged in and above the concave portion, the first inductor element variably changing an angle with respect to a horizontal surface of the substrate;
- a second inductor element, at least a portion of the second inductor element being arranged in and above the concave portion, the second inductor element being magnetically coupled with the first inductor element and varying an angle with respect to a horizontal surface of the substrate;
- at least one first piezoelectric actuator pair which variably controls the angle of the first inductor element;
- and
- at least one second piezoelectric actuator pair which variably controls the angle of the second inductor element.
