摘要： A workpiece retainer retains a workpiece at a time of a cutting process by a wire electric discharge machining device that cuts a workpiece by electric discharge from wire electrodes that are spaced from each other and are arranged in parallel. The workpiece retainer is formed with a fitting portion, into which the workpiece is fitted substantially without any gap, and has an external shape such that at a time of cutting the workpiece retainer together with the workpiece fitted in the fitting portion, a length along the wire electrodes of a portion where the workpiece retainer and the workpiece face the wire electrodes becomes substantially constant during the cutting process of the workpiece.
