PROBLEM TO BE SOLVED: To provide a rotary table for electrical discharge machining in which a current collecting tool is not provided to the front outer peripheral face of a table body regarding a rotary table device used for the electrical discharge machining. SOLUTION: The rotary table device is provided with a body, a spindle, which is pivotally supported to the body with a bearing and rotated by the rotational force of a driving source, the table body, which is fixed to the spindle via an insulator and has a table face for mounting a workpiece in the front, and the current collecting tool which is provided so as to be in contact with the table body and collects electricity made to flow in the workpiece during the electrical discharge machining. The table body is extended rearward from the bearing and provided with a shaft part whose diameter is smaller than the center hole of the spindle. The current collecting tool is provided to the shaft part so as to be in contact with it. COPYRIGHT: (C)2005,JPO&NCIPI
