PROBLEM TO BE SOLVED: To provide configuration capable of preventing the creep deformation of suspension wires in an optical switching device of a suspension wire system. SOLUTION: In the optical switching device of the suspension wire system, suspension wires 4 which support a movable body 2 on which a prism mirror 10 is mounted so as to be movable in an X direction and a Y direction in a cantilevered state are extended from a supporting base 12. Since these suspension wires 4 are used also as power feeding wires to driving coils 5, 6, tungsten wires having a high melting point and low resistivity are used as the suspension wires 4.
