To stably manufacture electrostatic capacitive elements having different capacitance without changing the shape of an electrode and the number of stacking of the electrodes.

The electrostatic capacitive element comprises a dielectric layer 12, a pair of or a plurality of pairs of electrodes consisting of one electrode 15 which is formed on one surface of the dielectric layer 12 and the other electrode 18 which is formed on the other surface of the dielectric layer 12 to sandwich the dielectric layer 12. One electrode 15 and the other electrode 18 are so arranged that the major axis directions of their electrodes cross each other. One electrode 15 and/or the other electrode 18 has at least two electrode widths. In one pair or a plurality of pairs of electrodes, if one electrode 15 is formed by shifting relative to the other electrode 18, the area of electrodes, overlapping in thickness direction of the dielectric layer 12, with the dielectric layer 12 in between, can be changed continuously or stepwise.
