PROBLEM TO BE SOLVED: To deodorize and sterilize a whole toilet room and reduce odors of ozone therein.SOLUTION: This sanitary washing device includes a body 200, a toilet seat 220, washing means 400, a deodorizer 600 for decomposing and removing odor substances contained in air in a toilet bowl, an electrostatic atomizer 800 for releasing air containing charged microparticle water created by electrostatic atomization of water, and a control device 700. When finishing the operation of the electrostatic atomizer 800, the control part 700 stops the operation of an electrostatic atomizing unit 830, and then stops a blower 820 after the passage of a predetermined time. Thereby, the function of all charged microparticle water generated by the electrostatic atomizer 800 is effectively utilized to effectively perform deodorization and sterilization of the whole toiler room, and ozone is diffused to be diluted to reduce odors of ozone as ill odors held by the ozone itself, thus keeping the toilet room comfortable.
