[PROBLEMS] To provide a sharp-edge grinding wheel, which can reduce damage to a workpiece and can maintain good cutting properties for a long period of time, and a process for producing the sharp-edge grinding wheel. [MEANS FOR SOLVING PROBLEMS] An Ni metal bonding material(3) with abrasive grains (2) disposed in a dispersed state therein is immersed in an etching liquid to selectively remove the metal bonding material (3) in its part in contact with the periphery of the abrasive grains (2) and thus to form a gap (4) between the periphery of the abrasive grain and the metal bonding material. Thereafter, a soft metal (5) is precipitated and grown from the metal bonding material in the gap (4) to fill the gap with the soft metal (5). According to the above constitution, the periphery of the abrasive grain (2) is covered with the soft metal (5), whereby a good cushioning function can be maintained for a long period of time and chipping can be suppressed.
