PROBLEM TO BE SOLVED: To provide a production method of a resin molded article by which a process line width is increased while a process time is reduced, and energy of irradiation light can be effectively used in a two-photon photo-fabrication method.SOLUTION: The production method of a resin molded article aims to produce a resin molded article by irradiating a photocurable resin with light, in which primary light is modulated to obtain secondary light and the secondary light is made to irradiate the photocurable resin. In the method, the primary light is modulated by controlling a topological charge given to the light to obtain the secondary light, and the irradiation intensity of the primary light is controlled to control the irradiation light of the secondary light. A process line width of the secondary light is preferably 0.2 to 4.0 μm.SELECTED DRAWING: None 【課題】２光子光造形法において加工線幅を拡張し加工時間を短縮するとともに照射する光のエネルギーを有効に活用できる、樹脂成形体の製造方法を提供する【解決手段】光硬化性樹脂に光照射を行い、樹脂成形体を製造する方法であって、第１次光を第２次光に変調し、該第２次光を光硬化性樹脂に照射することを特徴とする樹脂成形体の製造方法。前記第１次光に与えるトポロジカルチャージを調整し第２次光を変調し、第１次光の光照射強度を調整して、第２次光の光照射強度を調整する樹脂成形体の製造方法。好ましくは、第２次光の加工線幅が０．２〜４．０μｍである樹脂成形体の製造方法。【選択図】なし
