Abstract: Proposed is a vacuum carrier. The vacuum carrier includes a vacuum base having vacuum passages (20VP and 30VP) formed therein, the vacuum passages (20VP and 30VP) being connected to vacuum suction holes (24 and 34), and includes a vacuum unit configured to form a vacuum by suctioning air from the vacuum passages (20VP and 30VP) inside the vacuum base. Further, the vacuum unit includes a vacuum filling block (51) having suction ports connected to a vacuum apparatus, and includes a movement driving apparatus configured to move the vacuum filling block (51) such that the suction ports of the vacuum filling block (51) are connected to the vacuum passages (20VP and 30VP) inside the vacuum base.
