Abstract:
Provided is a film formation mask capable of preventing slit-like openings from being closed by vibrations so as to form a highly precise patterned film with stability. In a film formation mask formed by providing multiple slit-like openings in a metal foil, the shape of the opening of at least one end of the slit-like openings is asymmetrical with respect to a center line of the width direction of the slit-like openings.
