Abstract
Provided is a piezoelectric sound generating device capable of obtaining a stable connection state of lead-out conductors constituted of a conductive resin layer. A piezoelectric sound generating device, wherein lead-out conductorsare so flatly formed as to extend from surface electrodesof a piezoelectric elementexposed to first openingsto terminal electrodesof a terminal portionexposed to second openingson one main surface side of a diaphragm, respectively. As a result, the surface electrodeof the piezoelectric elementand the terminal electrodeof the terminal portion, and also the surface electrodeand a surface electrodeof the piezoelectric element, and the terminal electrodeof the terminal portionare conductively connected. Hence, poor connection caused by cracks or the like is not likely to occur in the lead-out conductors.
