Claim:
A sanitary washing apparatus configured to jet supplied water toward a human body, comprising: a washing nozzle including a jetting port configured to jet the water toward the human body; and a pressurizing device configured to pressurize the water and jet it from the jetting port, the sanitary washing apparatus being configured to perform a first jetting process having a first time span and a second jetting process having a second time span, jetting water by the first jetting process and jetting water by the second jetting process being alternately jetted from the jetting port, after performing the first jetting process, a prescribed waiting time being provided before performing the second jetting process, in the first jetting process, the pressurizing device making pressure of water subsequently jetted during the first time span higher than pressure of water previously jetted in the first jetting process so that the water subsequently jetted during the first time span overtakes and unites with the water previously jetted in the first jetting process at a prescribed position from the jetting port to form a first water mass, in the second jetting process, the pressurizing device making pressure of water subsequently jetted during the second time span higher than pressure of water previously jetted in the second jetting process so that the water subsequently jetted during the second time span overtakes and unites with the water previously jetted in the second jetting process at a prescribed position from the jetting port to form a second water mass, the pressurizing device making minimum pressure of water in the second jetting process higher than minimum pressure of water in the first jetting process and making maximum pressure of water in the second jetting process higher than maximum pressure of water in the first jetting process so that the second water mass is faster than the first water mass, and the prescribed waiting time between the first jetting process and the second jetting process being set so that before the first water mass impinges on the human body, the second water mass having faster velocity than the first water mass overtakes the first water mass to enlarge jetting water cross-sectional area of the first water mass.
