The invention relates to an angular displacement sensor, belonging to a sensor for measuring rotating angle. The angular displacement sensor solves the problem that the existing rotary potentiometer is hard to install when in angle measurement, and comprises a fixed component and a rotating component, wherein the fixed component includes an insulating base body and a conductive carbon film layer, and the circular-arc-shaped conductive carbon film layer provided with a nick is adhered to the surface of the ring-shaped insulating base body; the two circular-arc-shaped ends of the conductive carbon film layer are respectively provided with a positive electrode and a negative electrode; a signal output pole is arranged at the position corresponding to the circular-arc-shaped nick of the conductive carbon film layer on the insulating base body, and is welded with a V-shaped copper probe; the rotating component includes an insulating ring, a copper ring and an electric brush, wherein the copper ring is embedded and
