Abstract: PURPOSE:To form a vapor deposited film with high quality and good reproducibility while making a heat shielding body crack-free and preventing formation of the resulted product of reaction by constituting a ceramic crucible, heating element and heat shielding body in an element for vacuum vapor deposition in the state of having no contact with each other. CONSTITUTION:A heat shielding body 3 formed of alumina is disposed at the outside circumference of the high temp. heating part of a heating element 2 formed of spirally wound tungsten and a metallic mesh 4 is embedded in the outside surface thereof, in an element for vacuum vapor deposition. The terminals 2a, 2b of the element 2 are disposed at the opening ends of the body 3, and an annular support 5 for stabilizing a crucible 7 is disposed. The ceramic crucible 7 is freely attachably and detachably set in the body 3. If such device is used, the body 3 is made crack-free by the mesh 4. Since the element 2 is not embedded in the body 3, inter-wire short circuiting of the heating element and the contamination of the vapor deposited film are obviated as the formation of the resulted product of reaction by both bodies is prevented. The vapor deposited film is thus formed with high quality and reproducibility.
