Abstract: A suction device that holds a member by suction in a stable manner is provided. The suction device includes a columnar main body, a flat end face formed on the main body, a concave part formed in the end face, a fluid flow-forming means for forming a fluid swirl flow in the concave part by discharging fluid into the concave part, the fluid swirl flow generating negative pressure that applies suction to a member, and a linear guide groove formed on the end surface along a direction in which the fluid discharged into the concave part flows out of the concave part.
