Abstract: PROBLEM TO BE SOLVED: To provide a dry coating film formed of a smooth and thin film by forming photosensitive conductive paste with conductive powder of spherical particles having an average particle diameter, a coagulation rate and an average roundness in respective specific ranges, a glass frit and a photosensitive vehicle. SOLUTION: Smoothness of a line edge shape is secured by setting the average particle diameter of spherical particles to 1.0-4.0 μm, and the peeling off of a line during development due to insufficient curing of a coating film caused by degradation of ultraviolet-ray transmission is prevented. The coagulation rate of conductive powder is set to 2.0% or less, and the tenpoint surface roughness of a coating film surface provided by applying and drying photosensitive conductive paste formed by using it is reduced so as to prevent the occurrence of a crack in an electrode sheet. Additionally, the average roundness of the conductive powder is set to 96% or more so that the surface area of the coating film is restrained, and the expansion of the line caused by the diffusion of light is restrained. The conductive powder is mixed with a glass frit expressed by B-Bi-Si-Al-O and a photosensitivity-imparted organic vehicle, then dispersing them, and the photosensitive conductive paste is formed. Thus, a smooth dry coating film having a small film thickness can stably and surely be formed.
