PROBLEM TO BE SOLVED: To provide a resin bond type grinding wheel capable of suppressing emission of frictional heat by decreasing the grinding resistance and enhancing the anti-abrasiveness of the abrasive layer. SOLUTION: The abrasive layer 11 of resin bond type grinding wheel 10 is composed of a resin coupling phase 14 consisting of a thermosetting resin, for example a phenol resin, and super-abrasive grains 15 of diamond (or CBN, etc.), arranged dispresively in the resin coupling phase 14. A wear resistant filler 16, for example consisting of SiC, as a hard filler, hollow glass 17, and amorphous carbon 19 having a metal-covered layer 18 are installed dispersively in the resin coupling phase 14. The morphous carbon 19 is shaped spherical and furnished on its outer surface with metal-covered layer 18 consisting of a metal having a high terminal conductivity, for example Cu.
