PURPOSE: To provide a thin and flexible flat heater element excellent in homogeneity and durability by weaving a composite yarn mixedly twisted with a metal single yarn and a cotton single yarn into the substrate fabric of electrode sections continued from the substrate fabric of a heating section woven with a cotton yarn. CONSTITUTION: Electrode sections are formed at both end sections, and a heater section is formed between them on a substrate fabric to form a flat heater element. The substrate fabric of the heater section is woven with a cotton yarn. The substrate fabric of the electrode sections is woven with a composite yarn mixedly twisted with a metal single yarn and a cotton single yarn into the substrate fabric continued from the substrate fabric of the heater section, and it is formed to nearly the same thickness and flexibility as those of the substrate fabric of the heater section. The whole substrate fabric separately woven into the electrode sections at both ends and the heater section in the middle is coated with a conductive paint, and power connecting lines are provided on the electrode sections to form a flat heater element. The flat heater element is sealed in a soft vinyl chloride sheet with a heat sealer as required. |
