Abstract: There is provided a selective laser sintering method capable of reducing the trouble in chipping or breakage of the machining tool and the like. The manufacturing method according to an embodiment of the present invention is a method for manufacturing a three-dimensional shaped object by repetition of a powder-layer forming and a solidified-layer forming, the repetition including the steps of (i) forming a solidified layer by irradiating a predetermined portion of a powder layer with a light beam, thereby allowing a sintering of the powder in the predetermined portion or a melting and subsequent solidification thereof, and (ii) forming another solidified layer by newly forming a powder layer on the resulting solidified layer, followed by the irradiation of a predetermined portion of the powder layer with the light beam.
