Abstract
A first variable capacitance section included in a variable capacitance circuit includes a plurality of first variable capacitance elements connected to a signal line and each having a first capacitance value or a second capacitance value greater than the first capacitance value according to driving voltage, and includes a first fixed capacitance element connected in series with the plurality of first variable capacitance elements. A second variable capacitance section included in the variable capacitance circuit includes a second variable capacitance element connected to the signal line and having the first capacitance value or the second capacitance value according to the driving voltage, and includes a second fixed capacitance element connected in series with the second variable capacitance element.
