Abstract
A transfer apparatus using an electrostatic attraction includes an electrostatic chuck for attracting and placing a workpiece as a transfer member on a placement surface by electrostatic attraction. The electrostatic chuck is grounded by an earth via a ground electrode after the electrostatic chuck receives electric power from a power supply surface of a power source via power receiving electrodes of the electrostatic chuck, so that the electrostatic chuck is configured to attract and place the workpiece on the placement surface by electrostatic attraction in a state where electrostatic balance is broken.
