    摘要: PROBLEM TO BE SOLVED: To provide an electronic circuit including a variable inductor having a wider application range than the conventional one, and to provide an electronic device having the electronic circuit.
    SOLUTION: The electronic circuit includes a first inductor L
    1 , second inductors L
    2a to L
    2c , and current changing means SW
    a to SW
    c . The second inductors L
    2a to L
    2c are magnetically coupled with the first inductor L
    1 , and an induced current flows by a magnetic field generated by the first inductor. The current changing means SW
    a to SW
    c are connected to the second inductor L
    2a to L
    2c and are configured to change induced currents that flow through the second inductors L
    2a to L
    2c . The induced currents that flow through the second inductors L
    2a to L
    2c are changed to vary the inductance of the variable inductor 100.
