1. A method for slicing an ingot with a wire saw, comprising:
forming a wire row by a wire spirally wound between a plurality of wire guides and configured to travel in an axial direction of the wire;
feeding an ingot held with a workpiece-feeding mechanism to the wire row for slicing; and
obtaining a warp direction in a wire travelling direction of a wafer in a previous ingot slicing, and
slicing the ingot into a plurality of wafers while supplying a slurry to a contact portion between the ingot and the wire,
wherein the slicing occurs under a condition that a warp direction in a workpiece feeding direction of each of the plurality of wafers is identical to the obtained warp direction in the wire travelling direction.
