PROBLEM TO BE SOLVED: To provide a saw wire for a wire saw that facilitates wire extraction from a workpiece even in machining with a wire saw using bonded abrasive grains, and a machining method using the saw wire. SOLUTION: The wire saw is of a type having abrasive grains fixed to the wire 1 and machining a workpiece with the bonded abrasive grains, and the wire 1 has grainless portions 1-2 with no abrasive grains 2 fixed in a part or a plurality of parts. After the wire saw is used to cut the workpiece, when the wire 1 is extracted from the workpiece, the grainless portion 1-2 of the wire 1 is moved into contact with the workpiece, and the wire 1 in the region of the grainless portion 1-2 thereof is extracted from the workpiece. |
