PURPOSE:To enable the holding of a large amount of a molten substance in a crucible independently of the direction of spouting holes by dividing the crucible into a chamber contg. the molten substance and a vapor chamber with a partition wall having a communicating hole. CONSTITUTION:A crucible 1 is divided into a vapor chamber 6 confronting spouting holes 1a for spouting vapor of a molten substance 3 and a chamber 5 contg. the substance 3 with a partition wall 4, and a communicating hole 7 is pierced in the wall 4. Even when the spouting holes 1a are inclined from the vertical direction, no molten substance 3 flows cut, and only vapor is spouted. Accordingly, a large amount of the molten substance 3 can be held in the crucible 1 independently of the spouting direction.
