Abstract: A piezoelectric speaker has a piezoelectric element and vibration plate. The piezoelectric element has a base body with a mounting surface, as well as first and second terminals that are formed on the mounting surface with a distance between them. The vibration plate has a conductive body joined to the piezoelectric element and having a principle surface facing the mounting surface, as well as a first hole with or without a bottom which is formed on the principle surface in a region facing the first terminal to form a space between the body and first terminal. The piezoelectric speaker is capable of preventing the external electrodes of the piezoelectric element from shorting to each other.
