Abstract
An ultrasonic transducer includes: a piezoelectric element having a plate-like shape and an area expansion vibration mode; and a vibration surface separated from main surfaces thereof and arranged in parallel to the main surfaces so as to be brought into contact with a liquid; a piezoelectric element receiving portion held in contact with a side surface of the piezoelectric element and configured to fix the piezoelectric element; and a vibration transmitting portion; and the vibration member having a space for surrounding the main surface formed by the vibration surface, the piezoelectric element receiving portion, and the vibration transmitting portion, wherein a vibration generated by the piezoelectric element is transmitted to the vibration surface through the piezoelectric element receiving portion and the vibration transmitting portion, and the vibration surface is vibrated in a direction orthogonal to a vibration direction in the area expansion vibration mode.
