Abstract
To provide a multi-wire saw that, at the start of cutting of an ingot, prevents a wire from being displaced in grooves of guide rollers due to the wire being lifted. A wire is wound around a plurality of wire guide rollers to be positioned in a feeding direction of an ingot, and in this state, a wire-lifting restraining member that is a body of rotation and restrains the wire from being lifted by being brought into contact with the wire is disposed near the wire guide rollers.
