The invention relates to a capacitive displacement sensor, in which the adjacent emitting electrodes (12) in the same pitch T of the subsidiary scale are arranged on both sides of a reflecting electrode (11) respectively, the emitting electrodes (12) transmitting all the different signals are involved in a pitch T, and the geometric gaps of adjacent emitting electrodes (12) along the longitudinal direction of subsidiary scale are zero. In another pitch T separating several pitches T with aforesaid pitch, the arrangement of its emitting electrodes (12) is in alternation with the arrangement of above mentioned emitting electrodes (12). The fabrication difficulty and cost can be lowered, and the measuring precision can be improved.
