ンサ。[Scope of Claim for Utility Model Registration] (1) A case body of a rotation sensor provided opposite to a gear-shaped sensor rotor to detect the rotational speed of a rotating body, and a molded body on the detection end inside the case body. It is fixed by a member and includes a magnetoelectric transducer section that outputs a change in the magnetic field as a change in an electric signal due to a change in electrical resistance, and a magnet that is connected to this element. , or a composite of these. (2) The rotation sensor according to claim 1, wherein the protective layer has free-cutting properties. (3) The rotation sensor according to claim 1 or 2, wherein the protective layer is thicker than the gap between the sensor rotor and the outer surface of the detection end of the case body.
