A piezoelectric buzzer includes a piezoelectric diaphragm stored in a case having a case body and a back cover, and a pair of metal terminals which are electrically connected to the piezoelectric diaphragm and drawn out from the back cover. The metal terminals have terminal drawing portions, terminal fixing portions which are arranged along an inner surface of the back cover, and connecting portions which are bent from inner ends of the terminal fixing portions so that the bent portions are substantially U-shaped as viewed from above while forward ends thereof are separated from the inner surface of the back cover and brought into contact with the piezoelectric diaphragm.
