PURPOSE:To prevent resin from flowing out of a casting mold in time of vacuum casting by a method wherein a decompression container of flexible material is brought in contact with a casting mold by the use of the deformation of the decompression container of flexible material in time of decompression. CONSTITUTION:A casting mold 15 is located in a decompression container 11, vacuumized through exhaust holes 13, 14 and the decompression container of flexible material like sheet is deformed and compressed by atmospheric pressure and stuck closely so as to surround the circumference of the casting mold. The outer and the inner part of the casting mold are reduced in pressure and the circumference of the casting mold becomes nearly free from spaces and enables vacuum casting. Then, thermosetting resin is injected through the injecting inlet 12 and vacuum-cast.
