    Abstract: An electrostatic workpiece-holding method includes an initialization step, a static elimination step, a workpiece setting step, a workpiece attracting step, and a workpiece release step. The initialization step is a step of applying a positive voltage to electrode of the electrostatic attracting part while applying a negative voltage to electrode. The static elimination step is a step of removing the static charge on the surface of the electrostatic attracting part. The workpiece setting step is a step of placing the workpiece in contact with the surface of the electrostatic attracting part. The workpiece attracting step is a step of interrupting the application of the positive voltage to electrode of the electrostatic attracting part and the application of the negative voltage to electrode. The workpiece release step is a step of applying the positive voltage to electrode of the electrostatic attracting part while applying the negative voltage to electrode.
