    Abstract: An ultrasonic device according to one aspect includes a case, a piezoelectric element, a sound absorbing material, and a vibration-proof material. The case defines a housing space. The piezoelectric element is disposed in the housing space. The sound absorbing material is disposed on a main face of the piezoelectric element and is made of a foaming material. The vibration-proof material is disposed around the sound absorbing material. The sound absorbing material includes a first opposing face opposed to the main face. The first opposing face has an uneven shape in which a plurality of protruding portions and a plurality of depression portions are alternately continued, and is rougher than the main face.
