PROBLEM TO BE SOLVED: To provide a manufacturing method of a surface heating body 1 in which a uniform heat generation distribution is realized by preventing generation of holes by drawing bubbles and the manufacturing time can be shortened since the work does not require to be left standing for a long time and the automated line of the surface heating body manufacturing process is possible. SOLUTION: In a manufacturing method of a heating body, a conductive polymer which is melted in a solvent to become paste form or ink form, is printed over the face of a film 2 forming electrodes 3a, 3b. By drying the solvent through heating, and vulcanization a heat generating layer 5 made of the polymer is formed. Decompression treatment is done after the printing and before heating. |
