Abstract:
1. A method of manufacturing a formed article comprising 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 an entire surface of a lower surface of the forming material into tight contact with the forming surface, wherein the positioning of the forming material is conducted by supporting the forming material with a support member so that at least a portion of a lower surface rim portion of the forming material is in tight contact with the forming surface and a center portion of the lower surface of the forming material is separated from the forming surface, and the support with the support member is conducted so that the support member contacts with an entire circumference of the upper edge portion of the lateral surface of the forming material during the support in a state where a lower portion of a lateral surface of the forming material is separated from the support member.
