    Abstract: PROBLEM TO BE SOLVED: To provide a wire saw which prevents a workpiece portion cut into a wafer shape from moving like bellows by slurries scattering in a wire cut-in part on the workpiece side, and dropping from the side of a workpiece holding part, and improves warp of sliced wafers.SOLUTION: The wire saw includes: at least a wire which is wound on a plurality of grooved rollers to reciprocate in an axial direction; a nozzle for supplying slurries; a backing plate; and a workpiece feeder which holds a workpiece via a backing plate and a workpiece plate holding the backing plate and feeds them to the wire. The wire-saw supplies the slurries from the nozzle while pressing the workpiece held by the workpiece feeder against the wire to make cut-in feed, and cuts it into a wafer shape. The workpiece feeder has a workpiece holding part, and the maximum width of a lower end of the workpiece holding part is larger than a width of the workpiece to be cut.
