PURPOSE: An endless cutting wire manufacturing method for cutting an ingot is provided to prevent a wire from being wound tensely and a cutting wire from being cut in a high speed rotation by keeping the firm integrated connection. CONSTITUTION: An endless cutting wire manufacturing method for cutting an ingot is composed of the steps of: preparing seven or more strand wires(S), in which the strand wire is made by twisting tens of small-diameter thin wires(W) at the predetermined thickness; and making a large-scale diameter wire rope(R) by twisting seven or more strand wires. A twisting start point and a twisting end point of the seven or more strand wires are twist-started and finished at other positions. The strand wires are put in the center of other strand wires in twisting of the strand wires. Each twisting end point is put in the center of other twisted strand wires.
