PROBLEM TO BE SOLVED: To provide a thin-blade grinding wheel produced by electroformation whereby chipping of a work to be ground and the grinding resistance are reduced. SOLUTION: The body 1 of a grinding wheel is configured so that super- abrasive grains 4 of diamond, cBN, etc., and a filler 5 consisting of SiC, h-BN, and/or ceramics having a lower hardness and finer particle size than other abrasive grains are arranged dispersedly in a metal-bound phase 3 consisting of Ni, Co, and/or alloy thereof, wherein Young's modulus of the body of grinding wheel should lie within the range of 0.5-1.85×1011 N/m2.
