Abstract: A holding surface is formed by an inclined surface formed from the upper edge of a flange of a disk-shaped processing block to a workpiece portion. The processing block is accommodated in an annular holding member, a pressing-side holding member is advanced with respect to an accommodating side holding member, and the facing peripheral edge of the pressing side holding member is brought into contact with the holding surface. Since the facing peripheral edge abuts on a circle centered around the axis of the holding surface formed by a conical side surface, the axis of the annular holding member and the axis of the processing block coincide with each other in a processing apparatus, and the processing block is set at a predetermined position
