A warming device capable of quickly increasing a temperature of a washer fluid with a relatively-low current, warming a relatively-large volume of washer fluid, and further retaining a washer fluid in a warmed state for some time after a power supply is turned off is provided. A warming device includes a structure in which a small heating chamber is housed in an inner space of a heat-retaining hot fluid storage chamber and an electric heater is housed in an inner space of the small heating chamber. The heat-retaining hot fluid storage chamber has a heat-insulating structure. The small heating chamber has a moderate thermal conductivity. A washer fluid fed from a washer tank is supplied to the small heating chamber through the heat-retaining hot fluid storage chamber, warmed by the heater and ejected from a washer nozzle.
