A rotation sensor includes Hall elements 4 which detect proximity of a magnetic rotation body 3; a permanent magnet 6 which is adjacent to the Hall elements 4 to apply a magnetic field to the Hall elements 4; a main portion 1a on which the Hall elements 4, the permanent magnet 6, and a terminal 7 that is electrically connected to the Hall elements 4 are mounted; and a connector portion 1c in which terminal parts 7a for leading out the terminal 7 to the outside are incorporated. In the rotation sensor, the connector portion 1c is led out in a direction same as the placement direction of the magnetic rotation body 3 and horizontally to the magnetic rotation body 3.
