Claims (1)

[Scope of utility model registration request] A buzzer element 11 having a piezoelectric element 2 on the upper surface of a flat diaphragm 1, a lower case 3 that supports the periphery of the element 11 from below, and a lower case 3 that fits on the outer periphery of the lower case 3 and is connected to the case 3. An upper case 4 that holds the periphery of the buzzer element 11 therebetween, and a pair of pins 5b and 5a that are introduced into the lower case 3 from outside and whose tips contact the diaphragm 1 and the piezoelectric element 2, respectively. In the piezoelectric sounding body, the pins 5a and 5b are introduced into the bottom of the lower case 3 from the lower surface thereof, and are further led to the upper surface of the buzzer element 11 through the peripheral walls of the lower case 3 and the upper case 4. The distal end portions 16 of the arm portions 10 of the pins 5a and 5b, which extend substantially parallel to the element 11, are in contact with the piezoelectric element 2 and the diaphragm 1, respectively, on the upper surface side of the buzzer element 11. Piezoelectric sounding body.
