Abstract: The present invention is a soluble material for three-dimensional modeling that is used as a material of a support material for supporting a three-dimensional object when the three-dimensional object is manufactured by a 3D printer of a fused deposition modeling system and that contains a thermoplastic resin having a hydrophilic group and an organic salt compound represented by a general formula (I) below: (R1—SO3−)nXn+ (I). According to the present invention, it is possible to provide a soluble material for three-dimensional modeling that is used for a support material and that is capable of suppressing the degradation of the modeling accuracy of a three-dimensional object when the three-dimensional object is manufactured by a 3D printer of a fused deposition modeling system, and has a high rate of dissolution to neutral water to be removable speedily from a precursor of the three-dimensional object without use of a strong alkaline aqueous solution.
