Claims

[Claims for Utility Model Registration] 1. An upper metal plate having a downward protrusion in part;
It comprises a piezoelectric element, a lower surface metal plate having an upwardly protruding portion in part, and a frame-shaped resin spacer having a thickness greater than the thickness of the piezoelectric element, and the upper and lower surface metal plates are connected to the frame-shaped resin spacer. A piezoelectric component, characterized in that the piezoelectric element is fixed to the upper and lower sides of a spacer to form a case, and the piezoelectric element is housed in the case and is sandwiched between protrusions of the upper and lower metal plates. 2. The piezoelectric component according to claim 1, wherein the thickness of the frame-shaped resin spacer is smaller than the sum of the thickness of the piezoelectric element and the height of the protruding portions of the upper and lower metal plates. 3. The piezoelectric component according to claim 1 or 2, in which the electrodes of the piezoelectric element and the protrusions of the upper and lower metal plates are soldered. 4. The piezoelectric component according to claim 1, 2, or 3 of the utility model registration, in which upper and lower metal plates and a frame-shaped resin element are fixed with an adhesive.
