PROBLEM TO BE SOLVED: To provide a mounding agent for a model material with small dimensional increase by moisture absorption, solving problems in a conventional model material obtained by curing a displaying agent that the model deforms due to dimensional increase by moisture absorption, when using it as a master model or an inspection tool after a cutting process, and becomes useless as the inspection tool. SOLUTION: This mounding agent for the model material comprises a polyol, a polyisocyanate, a hollow microsphere and a dehydrating agent, and further comprises a fluorine-containing water-repellent agent.
