Abstract
In order to produce a larger output and smaller friction acting on a movable substrate of an electrostatic-type electromechanical transducer using electrostatic interaction between charged portions and opposing electrodes to transduce between electric power and motive power, the electrostatic-type electromechanical transducer includes: a fixed substrate; a movable substrate being movable while maintaining a predetermined distance between the fixed substrate and the movable substrate; charged portions disposed on a first surface of the movable substrate at intervals in a direction of movement of the movable substrate, the first surface facing the fixed substrate; opposing electrodes disposed on the fixed substrate in the direction of movement, the opposing electrodes facing the movable substrate; and a ground electrode facing a second surface of the movable substrate, the second surface being opposite to the first surface.
