Abstract
A variable capacitance device includes: (A) a first signal line that contains multiple first variable capacitance elements connected in series; (B) a second signal line that contains multiple second variable capacitance elements connected in series; (C) a first bias line used for applying a first direct-current voltage to each of the multiple first variable capacitance elements and multiple second variable capacitance elements; and (D) a second bias line used for applying a second direct-current voltage to each of the multiple first variable capacitance elements and multiple second variable capacitance elements. And, a part of at least one of the first bias line and second bias line is arranged so that it passes between two adjacent first variable capacitance elements among the multiple first variable capacitance elements.
