| abstract | A highly reliable ultrasonic device structure in which both ultra-wideband and transmission/reception efficiency are enhanced is provided. A substrate (11), a first electrode (21), a piezoelectric body (22), a second electrode (23), and at least each of a substrate (11), a first electrode (21), a piezoelectric body (22), a second electrode (23), and a first electrode (21), a piezoelectric body (22), and a second electrode (23), which are sequentially stacked in a stacking direction. An insulating layer 24 covering a part, a protective layer 25 covering the insulating layer 24, and a gap portion 30 formed in the substrate 11 on the side opposite to the piezoelectric body 22 with the first electrode 21 interposed therebetween. , the piezoelectric body 22, the second electrode 23, the insulating film 24, and the protective layer 25, the neutral plane of the strain of the laminated film 33 is the lamination in the center of the direction orthogonal to the lamination direction of the piezoelectric body 22 An electromechanical conversion element 18 located on the opposite side of the gap 30 from the intermediate position B in the stacking direction of the cross section of the film 33 .
