PROBLEM TO BE SOLVED: To perform fine fabrication on a surface while enough joining force to a base is obtained. SOLUTION: When a desired three-dimensional object is fabricated by making an organic power layer or an inorganic powder layer to be laminated on the base 21 be irradiated gradually with light beams so that the powder layer is melted/cured, the object to be fabricated is classified into a joint part 11 to be joined to the base 21, an upper surface part 13, and an intermediate part 12 between the joint part 11 and the upper surface part 13 and fabricated with light beam radiation conditions for each part changed. The joint part 11 which is to be joined to the base 21 is irradiated with light beams of large energy, and the upper surface part 13 to be fabricated finely can be irradiated with light beams of small energy according to the melting/adhesion conditions between the powder layers so that joining force to the base 21 is secured, and fine fabrication is performed.
