Abstract

PURPOSE:To make stable the sensor without lowering the sensitivity even under high temperature atomosphere, by making bonding through the use of glass in attaching the piezoelectric elements being the ultrasonic wave transmitting and receiving elements on the ultrasonic wave radiation plane or audio detection plane. CONSTITUTION:At the bottom surface of the cylindrical vessel 1 having the bottom of metal, the piezoelectric element 2 of disc shape of LiNbO3 is bonded by using the bond 3 consisting of glass material while drawing out the lead 21 externally. After that, the rear side of the vessel 1 is fixed on the transmission and reception plane 4 with weldering. By constituting the sensor like this and exciting the piezoelectric element 2 through the use of transmitter provided externally, this excitation is radiated externally through the bonded body 3, vessel 2 and transmission plane 4. In this case, since glass is used for the bonded body 3, the performance of transmission is made excellent, no peeling is caused, and lowering of insulation due to moisture is not caused.
