Abstract

A variable capacitance element is provided that includes a plurality of resistance elements that form a path for applying a control voltage to the electrodes of a plurality of variable capacitance portions connected in series. These resistance elements include first distribution resistance elements, second distribution resistance elements, a first shared resistance element, and a second shared resistance element. Moreover, vertical sectional areas of the first shared resistance element and the second shared resistance element with respect to conducting directions thereof are larger than the vertical sectional areas of the first distribution resistance elements and the second distribution resistance elements with respect to conducting directions thereof.
