Abstract
Provided are constituent particles containing a water-soluble material with high flowability in the form of powder, the constituent particles being capable of forming a support member that can be removed with a water-containing solvent in a process for producing a three-dimensional object. The constituent particles used for the production of a three-dimensional object each include a core and a shell that covers at least part of a surface of the core, the core containing a water-soluble material most abundantly, and a material contained in the shell most abundantly having a lower water solubility than the water-soluble material contained in the core.
