ABSTRACT:
A film-like molded body having a hollow portion of a predetermined contour and made from a disappearing material is formed first using a mold. Also, a disappearing model is prepared by dividing it into a plurality of disappearing model elements. Then, the disappearing model elements are placed so as to enclose the film-like molded body with the film-like molded body as a core and are bonded together and fixed using an adhesive. Accordingly, the disappearing model can be prepared easily while preventing the adhesive from being forced out into the disappearing model and dispensing with extraction of the film-like molded body.
