PIEZOELECTRIC COMPONENT

PURPOSE:To obtain the piezoelectric component with simple configuration and assembling by forming a case with three components of, a frame, an upper plate and a low plate and forming a piezoelectric element, a contact piece and an external terminal electrode to the case so as to be simply inserted thereto. CONSTITUTION:A piezoelectric element 22 is contained in a case 23 comprising a frame 28 forming a cavity 27 penetrated vertically, an upper plate 29 and a lower plate 30 respectively bonded to the upper and the lower end face of the frame 28. Contact pieces 31, 32 are arranged respectively between the piezoelectric element 22 and the upper plate 29 and between the piezoelectric element 22 and the lower plate 30 and the piezoelectric element 22 is supported with an interval with the inner face of the case 23 and the contact pieces 31, 32 are respectively in contact with electrodes 25, 26 of the piezoelectric element 22. External terminal electrodes 33, 34 extended up to the outer face of the case 23 are respectively formed and connected respectively to the contact pieces 31, 32.
