Abstract: An ultrasound unit includes: ultrasound elements each including a plurality of ultrasound cells formed on a substrate including a semiconductor, the plurality of ultrasound cells each including an upper electrode having a ground potential and a lower electrode to which a drive signal is applied, the upper electrode and the lower electrode being arranged facing each other via a cavity and thereby forming a first capacitor; a package member in which the plurality of ultrasound elements are disposed, the package member having a ground potential; and an insulation member disposed between the package member and each of the ultrasound elements. A second capacitor is formed as a result of the insulation member serving as a gap, and a capacity of a third capacitor serially connected to the second capacitor is smaller than a capacity of the second capacitor.
