Zusammenfassung:	A manufacturing method of a three-dimensional shaped object is capable of suitably forming a solidified layer by subsequent formation of a powder layer. The manufacturing method according to an embodiment of the present invention is performed by repetition of a powder-layer forming and a solidified-layer forming, the repetition including 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 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, wherein a light-beam condition for an irradiation path with an unirradiated portion on both adjacent sides thereof is different from that for another irradiation path with an irradiated portion at an adjacent region.
