An ultrasonic diagnostic apparatus according to an embodiment includes filter processing circuitry and generation circuitry. The filter processing circuitry performs a filter process of removing a still or minute-moving signal on reflected wave signals of an ultrasonic wave transmitted a plurality of times in the same scanning line. The generation circuitry generates reflected wave data through a phasing addition process using reflected wave signal of each channel after the filter process performed by the filter processing circuitry.
