1. A piezoelectric element comprising:

  • a multilayered structure in which a plurality of piezoelectric material layers and a plurality of internal electrode layers are alternately stacked, said plurality of internal electrode layers including a first group of internal electrode layers and a second group of internal electrode layers;

    first insulating films formed by using an aerosol deposition method, for covering said first group of internal electrode layers at a first surface of said multilayered structure;

    second insulating films formed by using the aerosol deposition method, for covering said second group of internal electrode layers at a second surface of said multilayered structure;

    a first external electrode electrically connected to said second group of internal electrode layers and insulated from said first group of internal electrode layers by said first insulating films at the first surface of said multilayered structure; and

    a second external electrode electrically connected to said first group of internal electrode layers and insulated from said second group of internal electrode layers by said second insulating films at the second surface of said multilayered structure.
