Abstract
An ultrasonic device includes nine ultrasonic array units arranged in a grid pattern of three rows and three columns, nine drive bypass wires that input and output drive signals to and from the respective ultrasonic array units, a first common bypass wire to which a common potential is applied, coupled to the eight ultrasonic array units, a second common bypass wire coupled to the ultrasonic array unit to which the first common bypass wire is not coupled, and a third common bypass wire coupling the first and the second common bypass wires. One of the drive bypass wires, the first common bypass wire, and the second common bypass wire is placed between the ultrasonic array units placed adjacent to each other. The third common bypass wire is placed inside of the ultrasonic array unit placed adjacent to the ultrasonic array unit coupled to the second common bypass wire.
