A sanitary washing apparatus includes a nozzle having jetting water outlets from which water that pulsates by cyclically changing pressure jets, and a pump and a controller that functions as a flowing water adjuster that adjusts flowing water fed to the jetting water outlets in such a manner that first jetting water and second jetting water alternately occur at peaks of the pulsation of the water. With such an arrangement the first jetting water hits an anus and the private parts of a human body in a smaller area with a higher density than the second jetting water, and the second jetting water hits the anus and the private parts in a larger area with a lower density than the first jetting water.
