A rotation sensor fixed to a sensor fixing member with simplified fixing system and excellent in water proofing property and vibration proofing property is provided. The rotation sensor includes a sensor unit having a magnetic sensor element for detecting rotation of a to-be-detected element provided in a rotating ring, a cable for drawing an output signal of the sensor element to the outside, and a substrate with an electroconductive region for electrically connecting the sensor element and a core line of the cable while the sensor element and the cable are fitted to the substrate. The substrate has at least one recess portion or projection portion engageable with a projection portion or recess portion in the sensor fixing member to fix the sensor unit to the sensor fixing member. A molding segment formed by molding is provided for covering the sensor unit.
