PROBLEM TO BE SOLVED: To provide a wire saw, optimizing the number of abrasive grains, the array interval of abrasive grains, and the projecting amount of abrasive grains to improve the cutting performance. SOLUTION: A projected image of the wire saw to which abrasive grains 23 are fixed to the periphery of a core wire 21 by bonding material is photographed, and according to the brightness of the projected image of the photographed wire saw, the contour of the wire saw is detected to detect the number of abrasive grains 23, the interval of the abrasive grains 23 and the projecting amount of abrasive grains 23. The respective values are optimized to manufacture the wire saw. When the wire saw is manufactured by this method, separation of bonding material can be prevented, the abrasive grain holding force is superior, and the cutting performance is improved.
