To use up a vapor deposition material maximally in a crucible used in an organic EL apparatus for vapor depositing the vapor deposition material on a substrate under vacuum.
The crucible has a box shape of a rectangular parallelepiped having a length nearly equal to one side of the substrate 10 in the longitudinal direction and is equipped with: a storing part 24 for storing the vapor deposition material at its inside; a heating means for heating the vapor deposition material stored in the storing part 24; and a cap body 26 arranged at the upper surface of the storing part 24 and having blowing-out ports 28 through which the vapor deposition material heated by the heating means to sublimate is blown out. The storing part 24 is partitioned into a plurality of compartments along the longitudinal direction by a plurality of partition walls 30, and each partition wall 30 is arranged apart a distance from the cap body 26 in such a manner that the heights of the partition walls arranged at the peripheral part become lower than those of the partition walls arranged at the central part.
