PROBLEM TO BE SOLVED: To provide a method of forming electrodes which simplifies the correcting step and omits the baking step. SOLUTION: The method comprises step 1 of patterning a thick film conductor material into specified shape, at least contg. a conductive powder, glass frit and thermoplastic resin, step 2 of heat treating at temp. selected in a range from the thermoplastic resin wt. reducing start temp. due to its thermal decomposition to the glass frit softening point, step 3 of testing the conduction of the heat treated conductor material, and step 4 of baking this material above the glass frit softening temp. After patterning the conductor material, part of the resin is baked off to make the material conductive while the electrodes are tested. This facilitates correcting short-circuited parts of the electrodes and allows broken parts of the electrodes to be corrected and baking of the electrodes laminated with insulation layers to be omitted. |
