PROBLEM TO BE SOLVED: To miniaturize an ultrasonic diagnostic device and to improve the precision of the ultrasonic diagnostic device. SOLUTION: The ultrasonic diagnostic device has ultrasonic transducers arranged in the state of strips, element selection switches connected to the respective ultrasonic transducers, a wave transmission circuit which drives a selected ultrasonic transducer and sends ultrasonic wages toward a patient, and a wave reception circuit which receives ultrasonic echoes from the patient by the ultrasonic transducer for performing wave reception processing and obtains the planogram of the patient. Between the ultrasonic transducers and the wave transmission and reception circuits, a switch for bundling the ultrasonic transducers the delay quantities of which are symmetric is provided.
