PURPOSE: A dial including contactless angle sensor is provided to reduce manufacture costs by using a rotor, which is made of synthetic resin, as a rotary shaft. CONSTITUTION: A dial including contactless angle sensor comprises a housing(10), a rotor(20), a rotational fixture, a hollow knob, a prism(50), and a cap(60). The rotor comprises a second joint groove, a fastening protrusion, a seating groove, a concavo-convex area, a prominence groove, an insertion groove. The second joint groove and fastening protrusion cope with a first joint groove of the housing. A magnet is settled in a seating groove. The rotational fixture is combined with the concavo-convex area of the rotor.
