摘要： A container of a material supply apparatus is configured of a crucible and an orifice. The crucible has a cylindrical shape, a rectangular-column shape or the like, and is hollow. Heat sources such as heaters are disposed around the crucible. The orifice including an opening is provided on a side of the crucible in a material element supplying direction. The orifice includes a pipe portion that extends in the material element supplying direction. The opening is formed on a tip of the pipe portion. An opening area of the pipe portion is formed to become gradually narrower towards the material element supplying side, namely in a direction of the opening.
