To provide a piezoelectric speaker in which a breakdown of an electric lead terminal is prevented when a large amount electric current flows into a thin narrow electrode lead terminal, any electric accident may be prevented in an electrode and a frame that would be likely to be touched by hands, the precision of position and shape of the electrode formed by using a mask is enhanced, and the generation of busy sound that becomes noise may be prevented at a predetermined frequency of the vibrating diaphragm, in the vibrating diaphragm, a side end of the vibrating diaphragm is clamped by wavy surfaces machined in at least one pair of plates to form a side frame the side frame is assembled with a vertical frame to form a frame, electrodes formed on the vibrating diaphragm are connected to each other by leads and the lead are fixed to the frame, whereby the vibrating diaphragm 1 may be firmly fixed to the side frame and concentration of electric current to local position of thin electrode lead terminals may be prevented.
