Abstract
The present invention relates to a method of manufacturing a formed article forming an upper surface of a forming material comprised of a thermosoftening substance into a desired shape by positioning the forming material on a forming surface of a mold and heating the forming material to a temperature permitting deformation to bring a lower surface of the forming material into tight contact with the forming surface. The forming is conducted while an exposed portion on the forming surface side of the mold upon which the forming material has been positioned is covered with a covering member. The present invention further relates to a covering member and a forming apparatus. According to the present invention, formed articles with a desired shape can be formed with high accuracy by preventing the contamination of upper surface of forming materials by foreign matter during forming.
