To provide a heat medium heater for a vehicle which achieves higher level of safety in terms of fail safe.SOLUTION: A heat medium heater for a vehicle includes: a heater: a heater case which stores the heater and heats a heat medium therein; and a heater electric power supply part which supplies electric power to the heater. A seal structure of the heater electric power supply part is provided on the heater case. The heater case includes a non-seal structure part which does not involve in the seal structure. The heater case comprises two or more kinds of portions having different heat-resistant temperatures and the non-seal structure part is formed by a portion having the lowest heat-resistant temperature.SELECTED DRAWING: Figure 1
