Abstract

PURPOSE: To obtain simplified constitution, by closely bonding the ferrite system stainless steel at the back of the piezoelectric element and commonly using this for the damper and the electrode.
CONSTITUTION: The plate shape conversion element 20 is closely bonded at the inner bottom of the metal case 11 in common use for one electrode via the contact media layer 30a. At the upper surface of the element 20, the damper 40 made of ferrite system stainless steel in common use with another electrode is closely bonded via the contact media layer 30b, the core wire 6 of the sheath wire 5 is connected to the top of the damper 40 and connected to one end of the power supply. Further, the insulator 7 is filled in the air gap in the case, and the cap 8 is screwed 9 to the case 11 after passing through the seath wire 5 to the center hole. The ferrite system stainless steel is increased for the temperature up to 1200°C under vacuum and gradually cooled to make coarse the crystal grains to obtain greater ultrasonic wave attenuation constant. The probe with simplified constitution but having the same degree of the performance of conventional ones can be obtained.
