During a process in which natural light taken from a light-collecting opening () propagates while repeatedly reflected by opposing reflecting surfaces of a reflecting plates (), by allowing seedlings p that are transplanted into the culture panel () to be irradiated with the light through a light-emitting hole () bored in the reflecting plate (), a culture object can be grown efficiently at a low cost by taking natural light from the outside.
