で、安価な構成とすることができる。Means for Solving the Problem In order to solve this problem, the present invention has a collar portion on the outer periphery and a diaphragm portion for generating ultrasonic waves in the center, and a horn portion for radiating ultrasonic waves. It is also possible to bond a piezoelectric ceramic vibrator to the diaphragm part of the vibrating member formed by connecting the collar part and the diaphragm part. Since it does not come into direct contact with the liquid, there is no erosion or corrosion, and no rubber backing is required when installing it in the bottom hole of the liquid tank, so the structure is simple and inexpensive.

Since it has the effect of acting as a sound wave emitting surface and does not need to be fixed to the liquid tank via a rubber backing, it can be an inexpensive vibrator. In particular, by connecting and integrating the horn part and the diaphragm part, the heat generated by the vibration energy of the vibrating part can be efficiently dissipated, and by establishing resonance conditions with the horn part, the vibration amplitude of the vibrating part can be reduced. It is possible to obtain the effect of easily increasing the
