An ultrasonic diagnostic apparatus in which an ultrasonic image of a puncture needle can be clearly captured. The apparatus includes: a reception signal processing unit for processing reception signals outputted from ultrasonic transducers; a reception beamformer for performing reception focusing processing on the reception signals to generate sound ray signals; an image signal generating unit for generating an image signal based on the sound ray signals; and a scan control unit for controlling a drive signal generating unit such that an ultrasonic beam with an intensity distribution having a center in a first direction is transmitted from a selected first group of ultrasonic transducers, and controls the reception beamformer such that an image signal representing an ultrasonic image in a second direction different from the first direction is generated based on reception signals outputted from a selected second group of ultrasonic transducers which receive ultrasonic echoes.
