Abstract
An electrode formation method for a solar cell to form an electrode of a base member, includes a screen printing process and a baking process. The screen printing process includes: mounting a metal mask on a surface of the base member, wherein the metal mask includes a covering portion configured to cover a part of a surface of the base member, opening portions configured to allow parts of the base member to be exposed therefrom, and bridge portions disposed along a direction intersecting with a longitudinal direction of circuit patterns between the opening portions; and supplying a paste to an upper surface of the metal mask by a squeegee head of a cartridge type, while relatively sliding a squeegee on the upper surface of the metal mask such that the squeegee travels relatively to the metal mask. In the baking process, the paste is baked to form the electrode.
