Abstract:
1. An actuator system comprising: a substrate moving in biaxial directions; a driving unit provided to face the substrate and moving the substrate in one axial direction of the biaxial directions; a holding unit provided to face the substrate and holding the substrate; a piezoelectric element provided to the driving unit and expanding and contracting in the one axial direction; a first electrode provided on a surface of the substrate on a driving-unit side; a second electrode provided on a surface of the driving unit on a substrate side and electrostatically adsorbing the first electrode; and a third electrode provided on a surface of the holding unit on a substrate side and electrostatically adsorbing the first electrode, wherein the driving unit is provided plurally in number and disposed in the one axial direction.
