A heating device for heating fluid is disclosed. The heating device includes a tanning unit including a thermistor element having a positive temperature coefficient characteristic and adapted to generate heat when electric power is applied thereto. At least one heat dissipating means having a plurality of through-holes defined therein is mounted on the heating unit in thermal conductive relation with the heating unit such that heat generated by the heating unit is transmitted to the heat dissipating means to heat fluid flowing through the through-holes. The thermistor element includes a pair of electrodes between which heating current flows. The location of the electrodes is chosen such that the current flows in a second direction, substantially perpendicular to the first direction.
