That is, according to the first aspect of the present invention, first, the inside of the negative pressure chamber is made to have a negative pressure by the flow of the compressed gas, and an attraction force is generated inside the suction portion, so that the substrate is attached to the attraction chuck. Adsorbed and fixed to Further, the compressed gas (exhaust Y) exhausted toward the exhaust pipe is blown out from the exhaust port between the substrate and the support surface through the exhaust passage, so that the exhausted compressed gas is wasted. The substrate and the support surface are easily separated from each other. Further, the compressed gas (exhaust Y) blown out from the exhaust port is supplied below the separated substrate, so that the substrate is stably held when the substrate is transported.
