PROBLEM TO BE SOLVED: To provide a rotation sensor which is easily manufactured because of a simple geometry of an elastic connection part, and reduced in a size of sensor itself. SOLUTION: The rotation sensor 1 comprises a rotor 2 mounted on a rotation part, and a stator 4 mounted on a fixing part; one of the rotor and the stator is connected to an electric contact; and the other is mounted an electric conductor connecting with the electric contact. The rotor 2 comprises: a first ring part 21 rotating around the rotation part; a second ring part 22 mounted outside of the first ring part; and the elastic connection part 23 consisting of a first connection part connecting to a radial direction with the first ring part and a second connection part connecting to the radial direction with the second ring part. The first connection part and the second connection part are arranged mutually in each center angle at about 90°different position against a center axis of the first ring part.
