Abstract: PURPOSE: To provide a molecular ray cell capable of preventing the generation of insulation failure at feed thorough parts due to the dropping of a film-forming material. CONSTITUTION: A crucible 2, a heater 3 disposed around the crucible 2, and heat-reflecting plates 5, 6 are supported on a base 1 and further supported with a cell flange 11 through an intermediate support board 8 and supports 9, 10.
