A radial-type magnetic encoder includes: an annular fixing member; and an annular plastic magnet attached to the annular fixing member. The annular fixing member includes the cylindrical portion, an outward flange portion extending outward in a radial direction from an edge of the cylindrical portion, and a sensor opposed portion bent from an edge of the outward flange portion and opposed to a magnetic sensor which detects rotation of the magnetic encoder, and the annular fixing member has a substantially U-shaped sectional shape along a plane including the radial direction and an axial direction. The annular plastic magnet has a shape that covers a front surface, a back surface, and an end edge of the sensor opposed portion, and an outer-diameter-side part of the outward flange portion.
