Abstract
An optical molding method includes the step of radiating a light flux onto a photocurable fluid substance while moving the light flux in such a manner as to draw a section of a target object so as to cure the irradiated portion. A plurality of light fluxes having different diameters is used in such a manner that only a light flux having a large diameter, or both a light flux having a large diameter and a light flux having a small diameter are used for a section having a thickness larger than the diameter of the light flux having a large diameter, while only a light flux having a small diameter is used for a section having a thickness smaller than the diameter of the light flux having a large diameter.
