PURPOSE:To provide a piezoelectric buzzer with tapering structure capable of easily performing packaging by using an automatic packaging machine as keeping the contact pressure of a connection terminal on a piezoelectric oscillation plate appropriately. CONSTITUTION:This buzzer is the piezoelectric buzzer 1 equipped with the piezoelectric oscillation plate 11, a case main body 12, and a pair of connection terminals 2 which energize the piezoelectric oscillation plate 11 by coming contact with it, and each of the connection terminals 2 is formed by connecting the outer terminal part 3b of an inside member 3 in which an inner terminal part 3a comes in contact with the prescribed part of the piezoelectric oscillation plate 11 elastically is connected to the inner terminal part 4a of an outside member 4 protruding to the outside piercing through the case main body 12 in the inside, and the outside member 4 is provided with prescribed required thickness in the packaging. |
