Provided is a three-dimensional shaping apparatus, method for producing a three-dimensionally shaped article, shaping solution for a three-dimensional shaping apparatus, and three-dimensional shaping powder making it possible to heighten the moisture resistance of a three-dimensional shaping powder and heighten the water resistance of a three-dimensionally shaped article. A three-dimensional shaping apparatus supplies onto a loading belt a three-dimensional shaping powder containing no adhesive such as a water-soluble polymer (S2). The three-dimensional shaping apparatus ejects a shaping solution onto the three-dimensional shaping powder from an inkjet head and thereby generates a layer including a product created by the three-dimensional shaping powder reacting with the shaping solution (S3). Layers are built up to produce a three-dimensionally shaped article of a desired shape. The shaping solution contains a surfactant, an adhesive, and a thickening/wetting agent for suppressing water evaporation and thickening the shaping solution; the three-dimensional shaping powder does not contain a water-soluble adhesive.
