Abstract: Provided is a wire saw (1) that cuts an ingot (I) while swinging the ingot. The wire saw (1) includes a first driving block (100), a second driving block (110), and an ingot holder (120). When the first driving block (100) moves, the second driving block (110) moves in a direction perpendicular to a moving direction of the first driving block (100), and simultaneously the ingot holder (120) is swung. The ingot holder (120) is transferred to a z-axial direction in which the ingot is cut by a lifting block (73), and the lifting block (73) moves independently of the first or second driving block (100 or 1110). Thus, the ingot (I) can be swung separately from the lifting block (73), and be inhibited from moving left and right. Since only the first driving block (100) is controlled, easy control and a simple structure are provided.
