This heat treatment was performed under a reduced pressure at a temperature of 700° C. Next, microwave heating was performed for three to thirty minutes at a temperature of 100° C. to 350° C. by microwave irradiation with a frequency of 5.8 GHz in a nitrogen atmosphere. This reduced a strain of the transparent electrode, and improved the conductivity or translucency of the transparent electrode.
