Claim 1:
2. The method for slicing an ingot according to claim 1, wherein
the warp direction in the workpiece feeding direction is matched with the warp direction in the wire travelling direction by causing a temperature adjusting function of the wire saw to control one or more of a temperature of cooling water flowing inside a wire saw casing which holds the workpiece-feeding mechanism, a temperature of cooling water flowing inside each of the plurality of wire guides, and a temperature of the slurry, and
the warp direction in the workpiece feeding direction and an absolute amount of warping in the workpiece feeding direction of each of the plurality of wafers cut out from the ingot are thus controlled.
