Abstract:
Provided is an electrostatic attraction apparatus in which a first insulating layer is formed on a base in an electrostatic chuck. A first portion of the first insulating layer extends on a first face of the base and a second portion of the first insulating layer extends on at least a portion of a second face of the base. An attraction electrode is formed on the first portion of the first insulating layer. A second insulating layer is formed on the first portion of the first insulating layer and the attraction electrode. A conductor pattern extends from the attraction electrode and provides a power supply terminal on the second portion of the first insulating layer. A contact part of a terminal member urged by an urging unit is in contact with the power supply terminal. The terminal member is connected with a wiring line connected to a supply power.
