Abstract
Provided is a suction device that can suppress sound and vibration during use. A suction device includes a flow-passage forming section () having a suction port () from which fluid is sucked, a discharge port () from which the fluid is discharged, and a flow passage () which is sealed from an outside except at the suction port () and the discharge port () and through which the fluid flows, and a piezoelectric driving part () that generates a flow of the fluid in the flow passage (). The piezoelectric driving part () includes a diaphragm () and a piezoelectric element () as a moving part that transmits driving force to the fluid. The moving part is entirely disposed inside the flow passage ().
