PROBLEM TO BE SOLVED: To provide a magnetized pulser ring having resistance to flaws improved by integrated injection molding of a magnetized body as a resin bonded magnet to a support member, shortening manufacturing processes, reducing costs, and preventing relative rotation of the magnetized body to the support member, which is problematic when using a resin bonded magnet. SOLUTION: Recesses 16, 17, 18 for relative rotation prevention for preventing the relative rotation of the magnetized body 12 are formed in a flange 14 of the support member 11. The magnetized body 12 is a resin bonded magnet. By a one-piece injection molding of the magnetized body 12 to the support member 11, protrusions 19, 20, 21 for relative rotation prevention fitted in the recesses 16, 17, 18 for prevention of the relative rotation of the flange 14 are formed in the magnetized body.
