Abstract
An object of the invention is to provide an ultrasonic probe, an ultrasonic diagnostic device, and a manufacturing method of the ultrasonic probe, which are capable of reducing a product defect rate. An ultrasonic probe according to one embodiment includes a plurality of channels. Each of the plurality of channels includes a vibrator that outputs an ultrasonic wave, and a transmission circuit unit that changes an output in response to an input transmission signal and causes the vibrator to output the ultrasonic wave by driving the vibrator with the output. Here, the transmission circuit unit includes a stop signal holding circuit that holds a stop signal when the stop signal is input in advance, and selects whether to change the output in response to the transmission signal based on whether the stop signal is held.
