There is provided a method for manufacturing a three-dimensional shaped object. The method of the present invention comprises the repeated steps of: (i) forming a solidified layer by irradiating a predetermined portion of a powder layer on a base plate 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; wherein the solidified layers are formed such that they have a high-density portion whose solidified density is 95 to 100% and a low-density portion whose solidified density is 0 to 95% (excluding 95%); and wherein the high-density portion is a portion of the three-dimensional shaped object, to which the force is applied when the three-dimensional shaped object is used.
