PROBLEM TO BE SOLVED: To provide a workpiece suction device including bellows pads, capable of, even when a cycle time for picking and placing operations of a workpiece is short so that high acceleration acts on the workpiece, performing stable and reliable suction over all steps of the operations. ! SOLUTION: Provided is a workpiece suction device 1 including bellows pads 2 used in picking and placing a workpiece W having a non-planar surface, in which a suction unit G mounting the bellows pads 2 is provided with lip pressing members A that are arranged along the outer slopes of lips 4 of the bellows pads 2 while the workpiece W is sucked and lifted by the bellows pads 2. Even when high acceleration acts on the workpiece W, the workpiece W is not dropped and residual vibration of the bellows pads 2 is not generated, thereby making it possible to quickly and stably perform the picking and placing operations of the workpiece from a workpiece supply place to a workpiece transfer place. !
