Zusammenfassung:	A metal shaped article production method includes a shaping data input step, a step of forming a constituent material layer using a constituent material, a step of forming a support material layer using a support material, a step of cutting a cut face in the constituent material layer of a stacked body formed by performing the constituent material layer forming step and the support material layer forming step, a step of degreasing a thermoplastic resin contained in the stacked body for which the cut face cutting step was performed, and a step of sintering metal particles by heating the stacked body, wherein in the support material layer forming step, the support material layer is formed so that a support face comes into contact with a face to be supported at an opposite side to the cut face at a position of the constituent material layer based on the shaping data.
