Metal foil mesh member for screen printing, screen printing plate, and method for producing solar cell using the screen printing plate

摘要

Provided is a metal foil mesh member for screen printing, which is capable of fine line printing with a printing line width of 39 μm or less and has sufficient strength that the screen printing plate is not easily broken, and a screen printing plate using the metal foil mesh member. To do. A metal foil mesh member for screen printing is a metal foil mesh member for screen printing made of a metal foil that is used by being integrated with a resin that forms a printing pattern, and is arranged along one direction of the metal foil mesh member. In the case where the opening width of the plurality of openings arranged at the pitch X is Y, and the rib is made of a metal foil sandwiched between two openings arranged along one direction, the thickness is cut along one direction. When the cross-sectional area of the rib is A, the opening width Y is 10 μm or more and 39 μm or less, the width C along one direction of the rib is 30 μm or less, and the cross-sectional area A of the rib is divided by the pitch X. The cross-sectional area B of the rib per unit length to be satisfied satisfies the relational expression of 3 (μm2 / μm) ≦ B (μm2 / μm). [Selection] Figure 3
