Claim 0:
1. An ultrasonic transducer for a measuring device that transmits and receives ultrasonic waves, comprising:
a housing container with a support body; and
a piezoelectric element with a substantially circular outer shape supported by the support body,
wherein the piezoelectric element includes;
multiple substantially sector-shaped oscillation parts that are divided by multiple grooves that communicate with each other at a central part and extend radially, and
soundproof sheets with double-sided tape arranged to fill multiple grooves in order to join and fix the multiple adjacent oscillation parts to each other so as to oscillate in a thickness direction in a first frequency band, as well as to oscillate in a radial direction in a second frequency band, which is lower than the first frequency band.
