A mask, through which a plurality of slender through-holes are formed, has a reinforcing section which is formed to span the through-holes, wherein recesses are provided at portions of the reinforcing section to cover the through-holes. Accordingly, a metal, which is subjected to the sputtering, easily makes the detour around the reinforcing section. Therefore, a metal film is easily formed even on portions shadowed by the reinforcing section. It is possible to accurately form a fine wiring pattern.
