SUPPORTING STRUCTURE FOR PIEZOELECTRIC VIBRATION BODY AND PIEZOELECTRIC TRANSFORMER, GYRO AND LAMINATED PIEZOELECTRIC BODY COMPONENT PROVIDED WITH SUPPORTING STRUCTURE OF PIEZOELECTRIC VIBRATION BODY

摘要

PROBLEM TO BE SOLVED: To provide the supporting structure of a piezoelectric vibration body, capable of improving the bonding strength of a conductive adhesive material and a mounted substrate, without lowering the elasticity of the conductive adhesive material and a piezoelectric transformer, a gyro and a laminated piezoelectric body component provided with a supporting structure of the piezoelectric vibration body. SOLUTION: A mounted substrate 11 is provided with terminal electrodes 12, 13 and 14 respectively on upper and lower surfaces, and respective through-holes 15, 16 and 17 are disposed at the center positions of the terminal electrodes 12, 13 and 14. After positioning a piezoelectric transformer element 6 on the mounted substrate 11 in a state of being separated from the upper surface of the mounted substrate 11 by a prescribed distance, a conductive adhesive material 21 is imparted to the part of a node N of the vibration of the input electrode 4 of the piezoelectric transformer element 6 and the terminal electrode 12 and also filled inside the through-hole 15 by a dispenser 25. Similarly, a conductive adhesive material 21 is imparted to an output electrode 5 of the piezoelectric transformer element 6 and the terminal electrode 14 and also filled inside the through-hole 17.
