Ultrasonic device, probe, electronic equipment, and ultrasonic image device

An ultrasonic device comprising:

• a substrate having an element array including a plurality of ultrasonic transducer elements arranged in an array form;
• an acoustic lens arranged on the substrate with a generatrix of the acoustic lens extending in a first direction;
• and
• a support member having a first surface facing and adhered to the substrate in an area including the element array, and a second surface facing an opposite direction from the first surface in a thickness direction of the substrate,
• the substrate defining a plurality of openings with each of the ultrasonic transducer elements being arranged in a corresponding one of the openings when viewed along the thickness direction of the substrate,
• each of the ultrasonic transducer elements including a vibration plate disposed between each of the ultrasonic transducer elements and each corresponding one of the openings, and
• a thickness of the support member between the first surface and the second surface being different at positions corresponding to centers of gravity of two adjacent ones of the ultrasonic transducer elements in the element array,
• the first surface of the support member being continuously flat, and
• the second surface of the support member defining a single, continuously inclined plane that forms an angle with respect to the first surface, the inclined plane being inclined in a second direction that is orthogonal to the generatrix of the acoustic lens, and the inclined plane corresponding to a plane connecting both ends of the second surface of the support member in the second direction.
