An ultrasonic transducer, including a piezoelectric element with physical characteristics of radial resonant frequencies and thickness resonant frequencies, and with an upper surface and a lower surface opposite to each other through the piezoelectric element and a lateral surface connecting the upper surface and the lower surface, and an acoustic matching layer set on the upper surface of the piezoelectric element and having a first resonant matching part and a second resonant matching part, wherein a thickness of the first resonant matching part in a direction perpendicular to the upper surface is greater than a thickness of the second resonant matching part in the direction, and the thickness of the first resonant matching part matches one radial resonant frequency of the piezoelectric element and the thickness of the second resonant matching part matches another radial resonant frequency or one of the thickness resonant frequency of the piezoelectric element.
