An ultrasound probe and an ultrasound diagnostic apparatus are disclosed. According to one implementation, an ultrasound probe includes the following. A plurality of transducers are arrayed in at least a predetermined first direction and transmit ultrasound to a subject to receive a reflected wave. A convergence unit converges the ultrasound transmitted and received by the plurality of transducers to the first direction. A switching element turns off transmission and reception of the ultrasound of some of the plurality of transducers arrayed in the first direction. A direction switching setter performs switching operation of turning on and turning off of the switching element to deflect in the first direction a transmission/reception direction of the ultrasound by the plurality of transducers.
