Abstract:
A variable distributed constant line includes a substrate, a signal line that is provided on the substrate, and includes a first line portion and a second line portion facing each other, a movable electrode that is provided above the substrate, and straddles both the first line portion and the second line portion in a manner to face the first line portion and the second line portion, and a driving electrode that is provided on the substrate in a manner to face the movable electrode, attracts the movable electrode by an action of a voltage applied between the driving electrode and the movable electrode, and changes a distance between the signal line and the movable electrode.
