PROBLEM TO BE SOLVED: To provide a high-quality ultrasonic image by suppressing deterioration of image quality due to ultrasonic attenuation. An ultrasonic diagnostic apparatus according to an embodiment includes a frequency characteristic analysis unit, a filter setting unit, and a filter processing unit. The frequency characteristic analysis unit acquires the frequency characteristic by frequency-analyzing the received signal at a predetermined depth based on the ultrasonic reception signal. The filter setting unit sets a reception filter that corrects the frequency characteristic of the predetermined depth so that the frequency characteristic of the predetermined depth indicates the predetermined frequency characteristic. The filter processing unit feeds back the reception filter to the reception signal having a predetermined depth and applies it.
