Rotation sensor accommodable to an eccentricity of a rotation portion of a member to be detected relative to a rotating shaft of the sensor
 There is provided a highly reliable rotation sensor which is capable of accurate detection of a rotation state. The rotation sensor comprises: a rotor rotating together with a rotation portion of a detection side; a first supporting member for rotatably supporting the rotor; and a detecting member secured to the first supporting member for detecting a rotation state of the rotor. The first supporting member is supported movably in both directions, that is, an X direction orthogonal to the direction of the rotating shaft of the rotor and a Y direction which is orthogonal to the direction of the rotating shaft of the rotor and orthogonal to the X direction.
