Abstract

PURPOSE: To prevent the change in the resonant frequency of the lead wire and to increase the durability of the connection, by fitting the piezoelectric element on the surface of the center of diaphragm plate, fixing the back side of the center on the support stand, and connecting the lead wire to the piezoelectric element of the fixed part.
CONSTITUTION: In the internal-combustion engine sensors, the thin plate shaped piezoelectric element 13 forming the electrode surface 14 is fixed on the surface of the center of the diaphragm plate 12 and the back side of the center is fixed to the support stand 11a so that the circumference of the diaphragm plate 12 is oxcillated. Further, the lead wire 15 for output pick up is provided at the fixed part of the support stand 11a for one electrode surface 14 of the piezoelectric element 13. Thus, since the lead wire 15 is fixed, the change in the resonant frequency due to the mass and spring action of the lead wire 15 can be prevented to increase the durability of the connection of the lead wire 15.
