The present invention relates to a liquid multilayer capacitive micro inclinometer, comprising at least two pairs of differential electrodes, each pair positioned in a same plane; at least one common electrode with a portion positioned in the plane of each pair of differential electrodes. The differential electrodes and the common electrode are provided in a sealed chamber, in which an immersing liquid is filled. The shape of the differential electrodes forms a sector of a circular plane. The inclinometer may further integrate a reading circuit. The present invention also discloses preparation method for the invented inclinometer.
