摘要： An object of the invention is to establish a mass-production type method for manufacturing in which a complicated shaped model with a hollow part can be molded integrally. The method for manufacturing a hollow model according to the present invention is a method for manufacturing a hollow model having a hollow part having at least one opening communicating with an outside, comprising: a core article forming process comprising a padding forming process for forming a padding made of a foamed material (B) and having a size acceptable to the hollow part and a film forming process for applying a film forming component (A) on the padding in order to form a film having an external form similar to said hollow part; a hollow model forming process that said core article formed in the core article forming process is set in a mold for forming an external form of the hollow model, two-component reaction rapid curing type urethane liquid resin (D) is injected into interstice between them to be cured, and then the hollow model having the core article inside thereof is formed by demolding; a padding removing process that organic solvent (E) is injected into the film comprising the film forming component (A) to dissolve and remove the padding comprising the foaming material (B); and a film removing process that the film from which the padding was removed is pulled up through the opening to remove.
