The axial-type magnetic encoder includes a wrap-around binding part wrapping around from a sensor-opposed surface to a back surface of an inward flange part of an annular fixing member. A separated inner peripheral part separated from a rotating body is formed at an inner diameter-side portion of the inward flange part while an outer diameter-side portion of a back surface of the inward flange part is abutted against the rotating body. The inner peripheral part of the annular plastic magnet wraps around to a back surface of the separated inner peripheral part.
