Claims

[Scope of utility model registration request]

In a piezoelectric buzzer having a structure in which a piezoelectric sounding element is housed in a resin case, and a metal terminal connected to the piezoelectric sounding element is fixed to the resin case by passing the protrusion of the resin case through a small hole and caulking, the protrusion is attached to the resin case. A piezoelectric buzzer characterized by having a recessed portion surrounding the base of the piezoelectric buzzer.
