1. A serial type planar heat-generating heater comprising a base substrate, an electrode plate, an insulating film, and a heating layer that are sequentially stacked from bottom to top,
wherein the electrode plate comprises a plurality of electrodes spaced apart from each other,
a plurality of perforated lines are formed in the insulating film to extend to surfaces of the plurality of electrodes,
the heating layer comprises a plurality of heating elements spaced apart from each other, and
both ends of each of the plurality of heating elements are respectively connected to a pair of adjacent electrodes through the perforated lines, thereby connecting all of the plurality of heating elements in series to each other.
