Abstract:
(EN) [Problem] To provide a dome screen that prevents the omission of stars projected on the dome screen. [Solution] A dome screen 10 on which an image can be projected has a dome part 11 and a sheet part 12. The dome part 11 has a plurality of holes, and is formed into a hemispherical shape. The sheet part 12 is disposed on the outer side of the dome part 11 so as to overlap with the dome part 11, and has light reflectivity.
