PROBLEM TO BE SOLVED: To provide a pulser ring without requiring manufacture of a new die for magnetization even when the size or form of a bearing or the like on which the pulser ring is mounted is changed. SOLUTION: This pulser ring is provided with a circular support member 7, and a magnetized body 8 comprising N-poles and S-poles arranged alternately and at constant pitch in the form of a band, that are fixed to an inner circumferential surface of a large diameter cylinder 7c of the support member 7. Length of a circumferential surface of the support member 7 is set to correspond to the length of the magnetized body 8 in such a way that their end parts are abutted on each other without a gap, and that magnetism at abutment parts J maintain the constant pitch.
