The ultrasonic image pickup apparatus includes a transmission/reception control unit that transmits an ultrasonic wave by applying a DC bias voltage and an AC driving voltage between electrodes of the electrostatic capacity type micro-machined ultrasonic transducer and picks up an image by transmitting and receiving two or more kinds of ultrasonic waveforms which have different signs, amplitudes, or phases from each other for one scanning line. In addition, as the AC driving voltage, the ultrasonic image pickup apparatus uses a voltage waveform that is obtained by adding a high frequency pulse waveform and a low frequency waveform that has a longer cycle than that of the high frequency pulse waveform and has such a voltage amplitude as makes the total voltage of the low frequency waveform and the DC bias voltage is equal or smaller than a pull-in voltage.
