Abstract
A variable capacitor comprising a plurality of variable capacitor elements each having depletion layer control sections and a capacity reading section formed on a semiconductor substrate so that the capacity appearing at each capacity reading section varies in response to the bias voltage applied to the depletion layer control sections, particularly characterized in that respective capacities appearing at the capacity reading sections are also varied due to the difference of distances between the depletion layer control sections and the capacity reading sections.
