Claim Text:
1. An ultrasonic device comprising: an ultrasonic element array substrate having a plurality of ultrasonic elements that each include a piezoelectric body and perform at least one of transmission and reception of ultrasound; an acoustic lens secured via an acoustic matching layer to a surface, formed with the ultrasonic elements, of the ultrasonic element array substrate, the acoustic lens having a lens portion that focuses the ultrasound; and a support member secured to a surface, opposite to the surface formed with the ultrasonic elements, of the ultrasonic element array substrate, wherein the support member is formed to have a larger area, in plan view in the thickness direction of the ultrasonic element array substrate, and a higher bending stiffness than the ultrasonic element array substrate, and the acoustic lens is formed to have a lower bending stiffness than the ultrasonic element array substrate.
