Abstract
A heating substrate useful in an electronic blanket or a hot compressing pad is provided. The heating substrate includes a flexible fiber layer and a graphite thread. The graphite thread is wound on the flexible fiber layer with a given winding distance. The graphite thread is stitched onto the flexible fiber layer by use of a positioning wire. A slot is formed appropriately on the flexible fiber layer for forming a given number of the graphite threads and the layer thereunder as a unit of the heating substrate of the invention. Thereby, the thick flexible fiber layer is prevented from being distributed unevenly when in use.
