To provide a piezo-electric vibration cone capable of preventing a conductive adhesive from fixing to an excitation electrode and performing stabilized and proper oscillation, and to provide a piezo-electric device using the vibration cone.

As for the piezo-electric vibration cone, excitation electrodes are formed on both principal planes of a rectangular and tabular piezo-electric blank. A drawing electrode is derived from the excitation electrode, and connection conduction is established between the drawing electrode and a vessel connecting electrode formed at least near the corner of a side plane at one short side of the piezo-electric blank. The drawing electrode is formed of the principal plane of a piezoelectric substrate via a side plane of its long side, and it is formed of the periphery of each excitation electrode on the front and the rear principal plane of the piezo-electric blank to the vessel connecting electrode where conduction is required to be established. In addition, conduction is established between each excitation electrode and a corresponding vessel connecting electrode through the drawing electrode.
