To draw an optional fine pattern on an abrasive grain electrodeposited layer by forming electrodeposition area groups having abrasive grains at a fixed pattern and recessed area groups having no abrasive grain on the mostouter surface of a grinding wheel.

An electrodeposited layer 24 constituted of electrodeposition area groups 22 having abrasive grains and recessed area groups 23 having no abrasive grain is provided on the surface of a grinding wheel 21. The electrodeposition area groups 22 holding abrasive grain groups by electrsodposition metal are formed high, and the recessed area groups 23 having no abrasive grain and only electrodeposition metal are formed low. Hereby, the electrodeposited layer 24 is formed with pockets by the recessed area groups 23, and hence it can rotationally grind a workpiece 27 to be ground while containing grinding liquid 28. Further, grinding abrasive grain groups are rollingly stuck on a thin film sheet through pressure sensitive adhesive, and hence an optional and fine patterned electrodeposited abrasive grain layer can be formed.
