PROBLEM TO BE SOLVED: To provide a metal die for magnet roll and a method of manufacturing a magnet roll, which can be mold a magnet roll having complicated magnetic force pattern, which is represented by a magnetic force pattern having the peak part of narrow half-value width and higher magnetic force and plateau type part. SOLUTION: Magnetization poles of mold molded with a metal die are formed, at least of a pair of magnets 10 which are provided opposed to each other, and magnetization distribution of this pair of magnets is formed in a V shape. |
