An ultrasound diagnostic apparatus including an ultrasound probe which outputs transmission ultrasound corresponding to a drive signal, which receives reflected ultrasound from the subject and which outputs a received signal according to the reflected ultrasound a drive signal outputter which outputs the drive signal to the ultrasound probe a hardware processor which controls the drive signal outputter to output a first drive signal having a first drive waveform and a second drive signal having a second drive waveform that is different from the first drive waveform a received signal generator which generates a first received signal based on the reflected ultrasound corresponding to the transmission ultrasound that is output based on the first drive signal and a second received signal based on the reflected ultrasound corresponding to the transmission ultrasound that is output based on the second drive signal and an extractor which extracts by arithmetic of the first received signal and the second received signal a received signal component which to be used in imaging. Frequency spectrums of the first drive signal and the second drive signal have a first intensity peak on a low frequency side of a center frequency of the transmission frequency, a second intensity peak on a high frequency side of the center frequency and a third intensity peak at a frequency between a frequency corresponding to the first intensity peak and a frequency corresponding to the second intensity peak, in a frequency band included in a transmission frequency band at −20 dB of the ultrasound probe.
