Abstract: A sanitary washing device includes a nozzle, a heat exchanger, a cold water flow channel, a switching element, a control board, a heat transfer plate, and a casing. The heat exchanger uses alternating current power to heat the wash water supplied to the nozzle. The cold water flow channel supplies the wash water to the heat exchanger from a water supply source. The switching element switches a supply state of the alternating current power to the heat exchanger. A controller is mounted to the control board. The controller is operated by direct current power. The controller controls the switching element. The heat transfer plate is configured to dissipate heat of the switching element. The switching element is mounted to the control board. The cold water flow channel includes a cooling part. The cooling part water-cools the heat transfer plate.
