The invention provides a capacitor structure, which comprises: a plurality of first leads parallel arranged in the conductive layer on a substrate separately, and divided into a first electrode group and a second electrode group, wherein the first leads of the first electrode group are alternately arranged with the first leads of the second electrode group; an insulation layer formed on the first leads and filled into the spaces between the first leads; second leads formed on the insulation layer electrically connected to the plurality of first leads in the first electrode group; and third leads formed on the insulation layer electrically connected to the plurality of first leads in the second electrode group. The capacitor structure of the invention achieves less capacitance interference and ensures more steady work.
