[Problem] To provide a resin-bond wire saw having good cutting performance and a long lifespan. [Solution] A resin-bond wire saw in which abrasive grains are fixed to the surface of the wire by a resin bond containing a novolac-type phenol resin, a resol-type phenol resin, and an amine-based silane coupling agent. The resin bond shows a plurality of peaks at intervals of 208 (m/z) that represent fragments in positive ions in MALDI-TOF-MS (mass spectrometry), and a peak that corresponds to a softening point at 175°C to 182°C in TG-DTA (differential thermal analysis). |
