Description 1 and title of the invention Ultrasonic waves after forming a plate of piezoelectric
vibrating material on an ultrasonic probe absorber and then forming slits on the piezoelectric
vibrating material plate at substantially equal intervals) to form a group of pressure vibration
1Ell elements An ultrasonic probe comprising an end portion of a piezoelectric vibrating material
plate which is not used as a compression vibration 111 element in the probe.

3. Detailed Description of the Invention The present invention relates to a probe for transmitting
or receiving ultrasonic waves. A probe used for mounting electronic fixed diet type i ?
sonication ilT forms an element group by arranging elongated piezoelectric vibrating elements
through an appropriate spacer, adheres this element group to an absorption plate, and molds
epoxy resin etc. on its surface To make the surface flat. This molding theory serves to insulate
the system from the "child dragon pole to the outside, fix the element, and sometimes double as
the T wave plate. By the way, since the width of this vibrator is usually less than one magazine, it
is very difficult to bond a plurality of tubes of confectionery together with the spacer to the
absorbing plate. It is also difficult to match the characteristics of the device. When performing
ladder tests, variations in element characteristics cause deterioration in directivity characteristics.
The present invention is directed to providing a probe that can be manufactured on a motor
vehicle and has the same characteristics of each element. Hereinafter, an embodiment of the
present invention will be described with reference to the drawings. In the first case, the
rectangular piezoelectric vibrating material plate l having the electrode mounted on the # 1
surface is fixed with an adhesive on the absorbing & 2 made of an ultrasonic absorbing material
such as rubber filled with ferrite, for example. . As shown in FIG. 2, the pressure '-vibration
material plate is provided with cuts 3 which reach the absorbing plate 2 at equal intervals
necessary for a very thin grinding wheel. A break that has been left between the cuts! The
portions of the ll L vibration material plate are respectively the piezoelectric vibration elements 4
(j, these elements form an element group. The elements 1, 5 and 5 left at both ends are not used
as elements to eliminate the end effect. In the above-mentioned cut 3, a layer 6 of a material
having a small rigidity and a small rigidity is used, such as silicon rubber. Furthermore, before
the film 7 of material whose acoustic impedance is as close as possible to that of a living body
such as urethane rubber or silicon rubber is attached to the surface of -6, and then the same as
above. Good. As described above, the present XAB / 4 ultrasonic probe cuts the piezoelectric
vibrating material plate attached to the absorber into the confectionery that makes up a group of
confectionery groups, so that it is possible to absorb individual elements as conventional
absorption plates It can be easily manufactured without the need for illustration work like
sticking. In addition, it is easy to make the characteristics of each element uniform. Furthermore,
in the present invention, since the remaining (end) portion of the piezoelectric vibrating material
plate which is not used as a vibrator element is left as it is, the end effect on the heat sink wave
transmission and reception directivity characteristics is removed and a good super There is an
effect that Tetsunami directivity can be obtained,
