PROBLEM TO BE SOLVED: To provide a workpiece handling method whereby the operations of supplying and discharging workpieces to and from a workpiece handling portion can be efficiently carried out while enhancing workability therefor. SOLUTION: Two workpiece holding hands 1J and 1K are rotated for reversal about a common rotation axis L relative to the arms of a working robot to switch around their positions whereby the continuous operations are made possible, after the workpiece W2 to be supplied to a workpiece stage 5A is held in one workpiece holding hand 1K and another workpiece W1 is discharged from the workpiece stage 5A by means of the other workpiece holding hand 1K, the workpiece W2 subsequently held in the one workpiece holding hand 1K is supplied to the workpiece stage 5A. The workability for the operations of supplying and discharging the workpieces W1 and W2 to and from the workpiece stage 5A is thus enhanced.
