Abstract
A planar heat generating device is made up of two heat radiating plates having through-holes, heat generating units of positive temperature characteristic material held between the two plates, two lead wires connected to the two plates, and an insulating cover layer of heat resisting synthetic resin which covers the two plates, the heat generating units and the connecting points of the lead wires. Fluid through-holes are formed in the parts of the insulating cover layer which are applied to the through-holes of the plates, so that the heat generated is effectively conducted to the fluid.
