PURPOSE:To manufacture flat heat generators at low costs regardless of their shapes. CONSTITUTION:A heat generator 10 is prepared in the form of a sheet by applying a mixture of carbon powder and silicone resin to a glass fabric. Then, electrodes made of copper foil or the like are attached to the heat generator 10. The electrodes 12 are disposed in parallel with edge electrodes 11 between the edge electrodes 11 at an equal distance determined in proportion to the resistance. After attaching the electrode 11 and 12 to the heat generator 10, both top and bottom surfaces of the heat generator 10 is covered with an insulating material. In use, the flat heat generator 10 is cut into strips as shown by lines 13. The cut edges are insulated and reinforced with adhessive tape. Every other electrodes are integrated to one terminal of a phase. The terminals are positioned opposite to each other, then connected to Teflon coated wires. |
