A sanitary washing apparatus (1) includes: a washing nozzle (82) and a pressurizing device (74). The sanitary washing apparatus being configured to perform first and second jetting processes alternately jetted with a prescribed waiting time there between. In the first jetting process, the pressurizing device makes pressure of water subsequently jetted higher than pressure of water previously jetted in the first jetting process so that the water subsequently jetted overtakes and unites with the water previously jetted in the first jetting process. In the second jetting process, the pressurizing device (74) makes pressure of water subsequently jetted higher than pressure of water previously jetted in the second jetting process so that the water subsequently jetted overtakes and unites with the water previously jetted in the second jetting process. The pressurizing device (74) makes minimum pressure of water in the second jetting process higher than minimum pressure of water in the first jetting process and makes 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. The prescribed waiting time between the first and the second jetting processes is 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.
