Provided is a photopolymerization device having the following: a base (16) in which a shaft insertion hole (16a) is formed; a workpiece retaining and rotating shaft section (20) that is inserted into the shaft insertion hole, is configured so as to be able to move in the axial direction relative to the base and able to rotate about a shaft, and that retains a workpiece (W) at one end; and a cover member (30) which has formed therein an opening (35) that can be closed by the base and in which a workpiece accommodation chamber (R) for accommodating the workpiece is formed when the base abuts a peripheral section (36) of the opening. The photopolymerization device, wherein after the base is caused to abut the peripheral section to form the workpiece accommodation chamber and the workpiece is rotated in a first region (R1) in the workpiece accommodation chamber, the workpiece retention rotating shaft is moved relative to the base to dispose the workpiece in a second region (R2) closer to a light projecting device than the first region, and control is performed so that the light projection device projects light to the workpiece located in the second region. |
