Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an apparatus that can improve application of powder having poor fluidity when manufacturing a three-dimensional object.SOLUTION: The apparatus for manufacturing three-dimensional object in a laminate type includes a formative chamber 10, the formative chamber 10 includes: a formative platform 6 which can adjust the height; the device 7 which applies a layer of material curable with the action of electromagnetic rays onto the formative platform 6; and an irradiation device for the irradiation of a part of the layer corresponding to the object 5. The irradiation device includes: a radiation source 1 which emits the electromagnetic rays; a control unit 3; and a lens 8 which exists in an optical path of the electromagnetic rays. The device 7 is configured in a shape of such a cylinder as to rotate for application of the layer, and the circumferential surface of the cylinder has at least a roughness Rz of 100 μm according to DIN EN ISO 4287:1998.
