PROBLEM TO BE SOLVED: To provide a wire saw capable of assuring bead retaining strength of a wire while reducing a diameter. SOLUTION: The wire saw 1 is an endless wire saw including cylindrical beads 5 consisting of super-abrasive grains 13 fixed to the outer periphery of a shank 11 which are arranged on the wire 3. In the wire saw 1, the diameter R of the bead 5 is 0.8 mm≤and≤5.0 mm, and a relation between a bead length L in the extending direction A of the wire 3 and a bead arrangement pitch P is 0.35<L/P<0.72.
