CONSTITUTION: A metal mask includes a concave part(140), an opening(150) and a partition wall(130). The partition wall includes a first to a third projection(130a~130c) and a connection part(130d). The connection part connects the first and the third projection. The concave part includes a first and a second concave part. The first concave part is formed by the first and the second projection. The second concave part is formed by the second and the third projection. The opening is formed by the first and the third projection and the connection part.
