A piezoelectric element comprises a metallic plate-shaped diaphragm, a plate-shaped piezoelectric body, and electrodes provided on both surfaces of the piezoelectric body, wherein one electrode being fixed to a main surface of the diaphragm. An extension electrode is extended onto a projection projecting from the diaphragm while it is insulated from the diaphragm. The extension electrode is extended from the diaphragm to the projection while it is insulated from the diaphragm. The extension electrode is electrically connected to the other electrode which is not fixed to the diaphragm of the piezoelectric body. The piezoelectric element is attached to a case while allowing a main surface of the projection on which the extension electrode is provided to direct outward. The case is fixed inside a housing of an electronic device, and the projection and the extension electrode are respectively electrically connected to circuit patterns of a printed circuit board mounted inside the housing by way of conductive portions provided on an elastic connection block. With such an arrangement, the case attaching the piezoelectric element thereto can be easily fixed to the electronic device and is easily connected to a circuit without trouble.
