In a wire saw, it is an object to reduce the variance in width of cut slices of a work as well as the degree of coarseness of the cut slices. A plurality of machining rollers 13 and 14 are arranged in parallel at prescribed intervals, and a large number of circular grooves 13a and 14a are formed on the outer periphery of each of the rollers. In an axial direction of the machining rollers 13 and 14, a plurality of supply reels 23, take-up reels 24 and wires 15A, 15B are arranged. The wires 15A, 15B supplied from the supply reels 23 are wound on the circular grooves 13a ad 14a of the plurality of machining rollers 13 and 14 so that they are travelled between the plurality of rollers 13 and 14, and taken up by the take-up reels 24. The work 20 is cut/sliced by a lapping operation of abrasive grains contained in the slurry which are supplied on the respective sets of wires 15A and 15B which travel between the plurality of machining rollers 13 and 14 in a longitudinal direction over respective halves of the rollers.
