At least one of the magnet blocks has mating means contacted with the corresponding mating means of the shaft, and an adjacent pair of the magnet blocks are bonded to each other in a positional relationship determined by mating means provided on the contacting surfaces of the adjacent blocks and by contact with the shaft surface. This magnet roll can be assembled very precisely without difficulty.
