摘要： Disclosed is a firing furnace for firing an electrode of a solar cell element, which is provided with: a transfer member, which transfers a substrate having a conductive paste applied thereto; a heating section, which heats the substrate and fires the conductive paste; and a cooling section, which cools the heated substrate. The furnace is also provided with a heating means for heating the transfer member. Specifically, at the time of firing the electrode paste using the wire-type firing furnace, since a wire is fired at a temperature substantially equivalent to the ambient temperature of the heating section, deterioration of yield due to having the electrode damaged by a deposited material of the metal component of the conductive paste is suppressed, said deposited material being deposited on the wire, and the wire-type firing furnace can be continuously used.
