PURPOSE: A wire saw coated with resin layers equipped with slopes is provided to form the slopes between beads, thereby securing spaces on the front sides of the beads in order to accommodate and discharge cut powder from a target. CONSTITUTION: A wire saw coated with resin layers equipped with slopes(31) comprises a wire(10), beads(20), resin layers(30). The wire is longitudinally and lengthily extended. The beads are arranged on the outer periphery at regular distances, and cuts a target(50). The resin layers are coated between the beads. The front side of the resin layer is fixed on the rear side of the front bead(20a), and the rear side of the resin layer is fixed on the front side of the rear bead(20b). The slope is such that the size of the front side of the resin layer becomes smaller toward the rear side of the resin layer, so that a space(32) is formed at the front of the rear bead. The front bead is supported by the resin layer. The bead comprises a sank surrounding the outer periphery of the wire, and a protrusive tip which protrudes from the outer periphery of the sank with a certain height. The bead is formed into a stereo shape such that the upper and the lower part of the bead are backwardly curved on the centers of both sides of the beads. The front bead is equipped on the outer periphery of the wire, and the second bead is equipped to be separated from the front bead, so that the slope is formed.
