Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate discomfort glare and uneven illuminance of a room lamp for a vehicle without decreasing the illuminance inside the vehicle or increasing power consumption. SOLUTION: A light transmitting part 3 placed between the inside of the vehicle and a light source 4 is formed by a synthetic resin to which a light diffusing agent is added. The light diffusing agent allows part of the light passing through the light transmitting part 3 equivalent to haze to be diffused to reach the inside of the vehicle. The luminance of the light source 4 inside the vehicle thereby decreases, thus eliminating the discomfort glare and uneven illuminance without decreasing the illuminance of the entire illumination surface.
