Original Abstract Submitted
An ultrasonic device includes a vibration plate having a first surface and a second surface opposite to the first surface, an acoustic matching layer that is provided on the first surface and is brought into contact with an object, a piezoelectric element provided on the second surface, and a prevention portion that is disposed in a manner of surrounding the piezoelectric element, and prevents vibration of the vibration plate. When a thickness of the acoustic matching layer is defined as t, a sound velocity of ultrasonic waves is defined as V, and a center frequency of ultrasonic waves transmitted from the first surface is defined as f, t≤V/f is satisfied.
