電発音体用振動板。 One electrode of a piezoelectric material having electrodes on both surfaces is connected to the recess of a metal vibrating substrate, which is formed by forming a recess with a flange that stands up around the periphery and further forming a band-shaped outer periphery around the upper end of the flange. At the same time, an insulating layer is formed on the surface from the other electrode of the piezoelectric material to the outer periphery of the metal vibrating substrate, and an extraction electrode is connected to the insulating layer to draw out the other electrode of the piezoelectric material to the outer periphery surface. In the diaphragm for a piezoelectric sounding body having the structure as described above, a slanted portion having an inclined surface is provided at least in a portion of the flange portion of the metal vibrating substrate where the insulating layer is formed. Board.
