An ultrasonic probe which includes multiple transducers arranged in an array and multiple element circuits that correspond to each of the multiple transducers and drive the multiple transducers, the ultrasonic probe having a first set of control lines connected to the multiple element circuits, a second control line commonly connected to the multiple element circuits, and a control circuit to which the first set of control lines and the second control line are connected. Each of the element circuits is configured from: a transmission reception circuit connected to the first set of control lines; an individual control circuit that controls the transmission reception circuit; and a branch line that branches off of a corresponding control line of the first set of control lines and is connected to the individual control circuit. The individual control circuit is connected to the branch line and the second control line. The individual control circuit switches the transmission reception circuit on and off individually on the basis of a signal from the branch line and a signal from the second control line. |
