Abstract

An ultrasonic transducer of this invention includes a supporting plate with concave portions and waveguides opened to first and second surfaces, respectively, a flexible resin film fixed to the supporting plate, and piezoelectric elements fixed to the flexible resin film so that their center regions overlap with the corresponding concave portions and their peripheral regions overlap with the supporting plate in a plan view, a vibrating body formed by the piezoelectric element and the flexible resin film has a resonance frequency of the lowest flexural vibration mode higher than a driving frequency of the piezoelectric element, and the supporting plate is configured so that a resonance frequency of the lowest flexural vibration mode of the entire of the ultrasonic transducer is higher than the driving frequency of the piezoelectric element.
