An ultrasonic diagnostic apparatus according to the present invention is an apparatus to which a probe with transducers is connectible. The apparatus includes a controller 100 which performs transmission processing for sending out an ultrasonic wave toward a subject by driving the probe 1 and reception processing for generating a received signal based on the ultrasonic wave that has been reflected from the subject and received at the probe and which performs, if a predetermined condition based on the received signal is satisfied, automatic freeze processing for stopping at least one of the transmission processing and the reception processing. The controller 100 restricts the automatic freeze processing for a predetermined period of time after having accepted a predetermined operating event.
