Abstract
An LC oscillator capable of oscillating even if it is fabricated on a substrate comprises a transistor, capacitor, and an inductor element 30. The inductor element 30 has two spiral conductors 120, 122 having substantially the same shape and formed on a semiconductor substrate 110. The inner end of the conductor 120 is electrically connected to the outer end of the conductor 122. Lead wires 130, 132 are connected to the outer and inner ends of the conductor 120 respectively. The lead wire 132 is passed through the lower conductor 122 and the semiconductor substrate 110 and led outside. The upper A conductor 120 serves as an inductor conductor and is connected to another component of the LC oscillator formed on the semiconductor substrate 110 through the lead wires 130, 132.
