SOLUTION: Inside an airtight housing 2 in the top end open port portion 3 of which a transparent plate 4 is embedded, there are arranged on a same axis L in order from a base end, a light source 5, a capacitor lens group 6, a film in which a plenty of stars are formed, a projection lens 8 movable toward an axial direction L, and the transparent plate 4. When the light source 5 is placed in a bathroom and is lit, a plenty of star dots are projected and irradiated on a predetermined wall and ceiling of the bathroom and a starlit sky is reproduced, and a focusing on the wall and the ceiling can be adjusted by moving and adjusting the projection lens 8 in the axial direction. The housing in which the light source 5 or the like are housed has a completely airtight structure, so that water and steam cannot permeate into it even if it is used in the bathroom.
