A capacitance element includes a first electrode, a second electrode, a third electrode, a fourth electrode, a first dielectric portion, a second dielectric portion, and a third dielectric portion. To the first electrode, a signal having a first polarity is applied. To the second electrode, a signal having a second polarity is applied. The second polarity is opposite to the first polarity. To the third electrode, the signal having the second polarity is applied. The third electrode is disposed on a position opposed to the second electrode. To the fourth electrode, the signal having the first polarity is applied. The first dielectric portion is provided between the first electrode and the second electrode. The second dielectric portion is provided between the second electrode and the third electrode. The third dielectric portion is provided between the third electrode and the fourth electrode.
