The invention provides a processing block, a processing block holder, and a method for positioning the processing block, which can easily align the axis of the processing block and the axis of a processing device when the disc-shaped processing block is supplied to the processing device. When a holding surface (1c) composed of an inclined surface is formed from the upper end edge of a flange part (1b), the diameter of which is larger than that of a part to be processed (1a) of a disc-shaped processing block (1), to the part to be processed (1a), the holding surface (1c) is formed into a conical side surface shape; when a processing block (1) is housed in an annular holding member (10) of a holding device, the processing block (1) is engaged with a pressing-side holding member (12) and advances toward a housing-side holding member (11), an opposite peripheral edge portion (12c) of the pressing-side holding member (12) is brought into contact with a holding surface (1c). The opposite peripheral edge portion (12
