A molecular beam epitaxy effusion cell, in which effusion material 5 is heated to melt down to be evaporated, so as to generate vapor molecule for growth of a thin film thereof upon a solid body surface, comprises: a crucible 1 for containing the effusion material 5 therein; and a heating means for heating the effusion material 5 contained within the crucible 1, wherein in the crucible 1 is contained heat conduction medium 4, being stable thermally and chemically and having heat conductivity higher than that of the effusion material 5, such as of pyrolytic boron nitride (PBN), together with the effusion material 5. |
