PURPOSE:To obtain a constant capacity according to the designed value without being affected by mechanical discrepancy by a method wherein the first protrusion for drawing-out an electrode is provided to one side of one conductor layer and the second protrusion of the this conductor is provided to the opposite side of the first protrusion. CONSTITUTION:A capacitor is composed of the overlapping parts of conductor layers 2 and 4. An electrode drawing-out part 8 is provided to the conductor layer 2 and an electrode drawing-out 9 is provided to the conductor layer 4. A protrusion 19 of the electrode 4 is formed on the opposite side to the first protrusion of the drawing-out part 9. Accordingly, when the descrepancy of relative position between the layer 2 and the layer 4 occurs, respective areas of the overlapping part 10 and overlapping part 20 change but absolute value of the change of each part is identical and the polarity is different, so that the total amount of area change is null and the total area is always constant. Thus the capacity value can be kept constant. |
