Patent ID: 8884720

Claim:
A capacitance element comprising: a first electrode to which a signal having a first polarity is applied; a second electrode to which a signal having a second polarity is applied, the second polarity being opposite to the first polarity; a third electrode to which the signal having the second polarity is applied, the third electrode being disposed on a position opposed to the second electrode; a fourth electrode to which the signal having the first polarity is applied; a first dielectric portion provided between the first electrode and the second electrode; a second dielectric portion provided between the second electrode and the third electrode; a third dielectric portion provided between the third electrode and the fourth electrode; a first external terminal connected to the first electrode and the fourth electrode; and a second external terminal connected to the second electrode and the third electrode; wherein the first dielectric portion is formed of a first dielectric layer, the first electrode is formed on a first surface of the first dielectric layer, and the second electrode is formed on a second surface of the first dielectric layer, the second surface being opposite to the first surface, wherein, when the first electrode is projected on the second surface on which the second electrode is formed, a projection pattern of the first electrode is overlapped with the second electrode, wherein the third dielectric portion is formed of a third dielectric layer, the third electrode is formed on a first surface of the third dielectric layer, and the fourth electrode is formed on a second surface of the third dielectric layer, the second surface being opposite to the first surface, and wherein, when the third electrode is projected on the second surface on which the fourth electrode is formed, a projection pattern of the third electrode is overlapped with the fourth electrode.
