Claims

[Scope of utility model registration request]

A pole piece 3 around which a coil 5 is wound is arranged at the tip of the magnet 2, and an alternating current voltage excited in the coil 5 is generated by the rotation of a magnetic rotating body 7 that is brought close to the tip of the pole piece. A rotation sensor for outputting an output, wherein the coil 5 is formed so that the number of turns of the wire gradually increases along the tip side of the pole piece 3.
