To provide a resin bond wheel improved in surface roughness while maintaining sharpness, hardly causing thermal damage to a cut material and abrasive grains and easily detecting contact with the cut material.
An abrasive grain layer 2 formed on a base metal 1 is formed in network structure wherein boundary parts between abrasive grains 3 and resin grains 4 and mutual boundary parts of the resin grains 4 are covered with layers 5 comprising carbon nanotubes formed of material with high electric conductivity and high heat conductivity. The formation of the abrasive grain layer 2 of network structure can be achieved by mixing such carbon nanotubes that the average grain diameters of the abrasive grains 3 and resin grains 4 are at least ten times as large as the diameter of the carbon nanotubes, in the abrasive grains 3 and resin grains 4. The layers 5 comprising the carbon nanotubes are formed to be connected to the base metal 1. This connection can be achieved by forming the mixed layer of the carbon nanotubes and resin beforehand on the base metal 1, and then forming the abrasive grain layer 2.
