The present invention provides a method for producing a three-dimensionally shaped moulded article, wherein a step (i) in which a prescribed portion of a powder layer is irradiated with a light beam to sinter or melt and harden the powder in the prescribed portion, and form a hardened layer, and a step (ii) in which a new powder layer is formed on the resultant hardened layer, and a prescribed portion of the new powder layer is irradiated with a light beam to form an additional hardened layer, are performed to alternately and repeatedly form powder layers and hardened layers. Notably, in this production method, a heating source element is provided inside the three-dimensionally shaped moulded article, the surface of the three-dimensionally shaped moulded article is formed so as to be uneven, and the main surface of the heating source element and the uneven surface are made to have the same shape as each other.
