CONDUCTIVE PASTE FOR GLASS SUBSTRATE, METHOD FOR FORMING CONDUCTIVE FILM, AND SILVER CONDUCTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a silver conductive film which can be fired at a low temperature of 400(°C) or lower, and is excellent in conductivity and adhesiveness to a glass substrate; a method for forming the same; and a conductive paste used for the same.SOLUTION: A conductive paste has such a paste composition that a ratio of a resin and silver is 12% or less and a ratio of the resin and a solvent is 35% or less using silver powder having an amount of rosin to be deposited of 1.6% or less and a particle size of 0.5 μm or less, and thereby is subjected to a firing treatment at a temperature in a range of 300-370°C to produce a silver conductive film 10 which has such good conductivity that a sheet resistance value is approximately 2-6 mΩ/square and has high adhesiveness to a glass substrate 12.SELECTED DRAWING: Figure 1
