This hygienic cleaning device (1) is provided with a nozzle (7), a water supply path (9), and a heat exchanger (10). The heat exchanger (10) has a casing (23), a flat plate-shaped heater (20), and a flow path space (25). The flow path space is formed in such a manner that the width of gaps measured on the inlet section side is less than the width of the gaps measured on the outlet section side. |
