PROBLEM TO BE SOLVED: To provide a driving device capable of operating in two directions and achieving miniaturization of a switch, and to provide the switch having the driving device. SOLUTION: An initial position of a first movable electrode 52 can be set up at a first initial position P1 and a second initial position P2 with a second driving section 2B. The first movable electrode 52 is located on the first initial position P1 at the time of an off-motion. When potential of a second fixed electrode 61 is set up at 5V, a rod 40 slightly moves to a left side since the second movable electrode 62 is attracted at a second fixed electrode 61 side with electrostatic force, and the first movable electrode 52 is displaced at the second initial position P2. Furthermore, when potential of the first fixed electrode 51 and the second fixed electrode 61 is set up at 5V, the rod 40 largely moves to the left side since the first movable electrode 52 is attracted at a first fixed electrode 51A side. Moreover, when potential of the first fixed electrode 51 is set up at 5 V at the time of an off-state, the rod 40 largely moves to a right side since the first movable electrode 52 is attracted at a first fixed electrode 51B side with electrostatic force.
